1. Executive summary
The Capybara wildfire model places a moderate but operationally critical 21-day fire-risk surface across Utah, concentrated along the Wasatch Front foothills, Cache Valley, the central-Utah alfalfa belt (Sanpete, Sevier, Beaver), and southwestern Utah (Iron and Washington counties around Cedar City). Population exposure is modest at 1.45 percent (≈28,087 of 1.94 M mapped) — Utah's populated corridor sits adjacent to the high-posterior surface rather than fully inside it.
The model's read is corroborated in real time. The Cottonwood Fire (Beaver County, started 22 June) had grown to ~59,613 acres at 0 percent containment on the day this report was written, with Gov. Spencer Cox describing it as potentially "the most destructive in state's history." The Iron Fire (Juab County, started 13 June) has burned 37,172 acres at 17 percent containment, with all of Eureka under mandatory evacuation. Five additional active fires (Sawmill, Bonneville, Hasting, Mill Hill, Sardine Canyon) are burning across the geography the model flagged.
One operator-specific finding: 3.59 percent of mapped solar farms (1 of 28 sites) sits inside the posterior, almost certainly the 240 MW Escalante Solar Project ~5 miles north of Milford in Beaver County — the same county as the Cottonwood Fire.
2. Exposure analysis
| Variable | % of total | Expected (absolute) | Total (denominator) |
|---|---|---|---|
| Population (expected exposed) | 1.45% | 28,087 ppl | 1,941,338 ppl |
| Cropland area (expected exposed) | 12.35% | 32,096 ha ⚠ | 259,910 ha ⚠ |
| Urban area | 0.76% | 1,181 ha ⚠ | 155,673 ha ⚠ |
| Oil palm area | N/A — not present in AOI | ||
| Protected areas | 0.87% | 24,094 ha ⚠ | 2,774,200 ha ⚠ |
| Built-up footprint | 2.03% | 445,062 ha ⚠ | 21,966,264 ha ⚠ |
| Electric grid length | 3.78% | 341 km ⚠ | 9,013 km |
| Roads length | 3.22% | 520 km | 16,127 km |
| Oil & gas sites | N/A — sparse-point artefact | ||
| Wind farms | 0.01% | 0 sites | 5 sites |
| Solar farms | 3.59% | 1 site | 28 sites |
Robust headlines: Cropland 12.35 % is the standout — 8× the population rate; this is a crop-and-rural-land risk surface. Solar 1-of-28 is a specific-operator finding worth direct dispatch. Population exposure is moderate but small central-and-southern county communities (Beaver, Eureka, Cedar City, Ephraim) carry disproportionate risk for their size.
3. Spatial findings by zone
| Beaver / Iron / Millard — CRITICAL · ACTIVE | The model's brightest single cluster. Cottonwood Fire (~59,613 ac, 0 % contained) + Sawmill Fire (3,760 ac, 20 % contained). Escalante Solar Project in Beaver County. |
| Juab County (Eureka) — CRITICAL · ACTIVE | Iron Fire (37,172 ac, 17 % contained, all of Eureka evacuated). Rangeland + dryland-wheat fringe. |
| Sanpete / Sevier alfalfa corridor — CRITICAL · ACTIVE | State's densest alfalfa and dairy-feed geography. Mill Hill Fire (Sanpete) active. Producers report fields "looking like late summer" in early June. |
| Wasatch Front foothills — HIGH · ACTIVE | Bonneville Fire (U of U foothills) + Hasting Fire (Tooele). Wildland-urban interface dominant. |
| Cache Valley — HIGH · ACTIVE | Grain-belt and alfalfa. Sardine Canyon fire sparked near summit. |
| Washington County — HIGH | Southwestern desert margin; specialty stone-fruit and wine grape producers. |
| Box Elder / Utah orchard belt — NOT IN FIRE POSTERIOR | Important context: this is Utah's orchard county, but its 2026 disaster is the April hard-freeze, not fire. Crops already lost. |
4. Crop-focused analysis ★
This is the section the run was commissioned for. Utah agriculture is being hit on three independent axes in 2026, and the wildfire model captures one of them directly.
4.1 — Utah cropland snapshot (what the 259,910 ha actually is)
The model's mapped cropland covers Utah's irrigated agricultural footprint. By acreage and economic weight, this is heavily dominated by:
- Alfalfa / hay — Utah's largest crop by acreage; highest alfalfa per-acre yield in the United States. Concentrated in Cache, Sanpete, Sevier, Millard, Beaver, and Iron counties. Feeds Utah's beef cattle, dairy, sheep operations + major export hay sector (China, Middle East).
- Wheat and barley — Cache Valley and northern Box Elder.
- Corn (silage) — paired with the dairy operations in Cache and Sanpete.
- Stone fruit and orchards — Box Elder (peaches), Utah County (sweet cherries, apples), Washington County (peaches). WIPED OUT in April 2026 (see 4.3).
- Onions, sweet cherries, specialty crops — small-acreage but high-value pockets in Box Elder and Cache.
- Range and pasture — not in the cropland mask but operationally adjacent; supplies Utah's beef cattle and sheep flocks.
4.2 — The 12.35 % cropland overlap IS the alfalfa belt
The 32,096 hectares the model flags is almost entirely the central-and-southern Utah alfalfa corridor — Sanpete, Sevier, Beaver, Iron, Millard counties — plus the Cache Valley grain-and-alfalfa belt. These are precisely the counties carrying the largest active fires (Cottonwood, Iron, Sawmill, Mill Hill) and the most-stressed irrigation systems.
4.3 — The April 2026 hard-freeze orchard cascade
Independent of wildfire, Utah's orchard sector was devastated in April 2026 by a hard-freeze event after the warmest winter in 131 years:
- 95–100 percent loss across peaches, cherries, apricots, apples, pears in Box Elder and Utah counties.
- Grays Orchard closed for the entire 2026 season (Utah Farm Bureau).
- Gov. Cox signed an agricultural emergency order on 15 May 2026 for orchard freeze damage.
- Utah Farm Bureau + Deseret News forecast a "fruit famine" for Utah-grown peaches, cherries, apricots, apples through summer 2026.
Why this matters for the wildfire report: it is the second crop disaster of the year, disproportionately affecting small-orchard family operations with the thinnest financial margins for recovery. Orchards are not currently in the high-posterior wildfire surface, but a smoke-taint event from drift smoke from the central-Utah fires would compound damage on already-reduced harvests.
4.4 — Compound-disaster summary by crop type
| Crop type | 2026 disaster status | Geography |
|---|---|---|
| Alfalfa / hay | ACTIVE — fire + drought | Sanpete, Sevier, Beaver, Iron, Cache, Millard |
| Wheat / barley | Drought-stressed | Cache Valley, northern Box Elder |
| Corn (silage) | Drought + irrigation curtailment | Cache, Sanpete |
| Stone fruit / orchards | 95–100% LOSS — Apr 2026 freeze | Box Elder, Utah, Washington |
| Range / pasture (beef + sheep) | BLM Stage 1 fire restrictions | Juab, Millard, Sanpete, Sevier, Wayne, Piute, Box Elder, Cache |
| Specialty (onions, sweet cherries, wine grapes) | Mixed (freeze + fire-adjacent) | Box Elder, Utah, Washington |
4.5 — Operational recommendation
For UDAF, Utah Farm Bureau, and the affected cooperatives:
- Recognise this as a triple-shock year — drought + April freeze + active wildfire. Federal disaster declarations may need to stack.
- Prioritise the alfalfa corridor for fire-perimeter inspection, irrigation-system continuity, and immediate evacuation-planning support. Lost cuttings are recoverable; lost equipment, livestock, and outbuildings are not.
- Don't write off Box Elder and Utah County orchards from 2027 planning — trees are still alive in most cases; the issue is this year's harvest. Disaster-relief programmes should bridge growers to 2027, not encourage exit.
- Range and pasture leaseholders should expect Stage 1 restrictions to escalate to Stage 2; pre-position herd-movement plans.
- Smoke-taint testing for any wine grape and remaining stone fruit downstream of the central-Utah fires is worth funding proactively.
5. Forecasting and Decision Objects (FDOs) — JANUS method
FDOs follow the JANUS analytic method (Feged 2025, DOI 10.21203/rs.3.rs-7580516/v1).
Model-derived FDOs
FDO 01 — 32,096 ha of Utah cropland inside the 21-day posterior (12.35 % of mapped)
| Source / trace | MODIS MCD12Q1 LC classes 12 + 14 (cropland) fraction-preserving aggregation at exposureScale = 1000 m, posterior-weighted via the single-pass exposure stack. |
| Simple | About one in eight hectares of Utah cropland sits inside the 21-day fire-risk surface. Eight times the population exposure rate. |
| Expert | Unusually high cropland-to-population exposure ratio for a Capybara run. Geographic concentration in Sanpete / Sevier / Beaver / Iron / Cache valleys — the state's alfalfa belt — drives the signal. |
| Implication | UDAF and Utah Farm Bureau should treat the next 21 days as a state-wide elevated alert for hay producers. Federal Pasture, Rangeland, Forage (PRF) insurance triggers may activate. |
FDO 02 — Solar-farm exposure 1 of 28 (3.59 %) — almost certainly Escalante Solar Project
| Source / trace | WRI/GPPD/power_plants filtered to solar fuel types. Posterior-sampled at point locations. Beaver County match. |
| Expert | The Escalante Solar Project (240 MW AC, ~1,900 acres, ~5 mi N of Milford) is the most likely match given Beaver County location and active Cottonwood Fire footprint. Enterprise Solar Farm (80 MW AC, Iron County) is secondary candidate given Sawmill Fire activity. |
| Implication | Operator should activate fire-perimeter inspection, panel-debris-monitoring, and access-road clearance protocols. Rocky Mountain Power / Berkshire Hathaway Energy should anticipate possible upstream disruption to generation feed-in. |
FDO 03 — Six concurrent active fires across the model's flagged geography
| Source / trace | Capybara active-fires layer (FIRMS, last 7 days) showing clusters in Beaver, Iron, Juab, Sanpete, Salt Lake County, Cache County. |
| Implication | The Capybara map can be shared with Utah Division of Emergency Management as a complement to NIFC's national fire-perimeter dataset — adds the forward-looking posterior surface alongside the active-perimeter data. |
Media-triangulation FDOs
FDO 04 — Cottonwood Fire (Beaver County) validates the model's brightest cluster
| Source / trace | Cottonwood Fire: started 22 June, ~59,613 ac at 0 % containment by 24 June, Gov. Cox described as potentially "most destructive in state's history." Mandatory evacuations at Eagle Point Resort, Merchant Valley, HiLo Estates, Arrowhead Summer Homes. SR-153 closed. Human-caused. 50 mph wind gusts. |
| Simple | The model's brightest cluster in Beaver County is exactly where the largest active fire in Utah is burning. |
| Implication | The single highest-confidence convergence finding of the run. Capybara identifies Beaver as the brightest single cluster from independent EO data — and that county now hosts what the Governor calls potentially the most destructive fire in state history. The model could have flagged the Beaver corridor 21 days before the fire started. |
FDO 05 — Iron Fire (Juab County) validates the northern signal
| Source / trace | Iron Fire: started 13 June near Boulter Peak, 37,172 acres at 17 % containment by 23 June, all of Eureka under mandatory evacuation, Elberta on READY status. |
| Implication | Second major fire matches the model. Utah Division of Emergency Management's geographic priorities and the Capybara model output are now triangulated by two independent megafires inside a 10-day window. |
FDO 06 — Compound disaster: April 2026 hard freeze wiped out Utah orchards independently
| Source / trace | Utah Farm Bureau and Deseret News reporting on the April 2026 hard-freeze event: 95–100 % loss on peaches, cherries, apricots, apples, pears across Box Elder and Utah counties, after warmest winter in 131 years. Gov. Cox signed state agricultural emergency order on 15 May 2026. |
| Simple | Utah's orchard sector lost most of its 2026 fruit in April. The wildfires are now hitting alfalfa and rangeland producers. Two separate disasters in one year. |
| Expert | The April freeze and the June fires are climatologically connected — the warmest winter in 131 years drove both the early-flowering vulnerability and the record-low snowpack that produced the drought that produced the fire conditions. Two manifestations of the same anomalous winter. |
| Implication | Federal disaster relief for Utah agriculture in 2026 needs to stack two declarations: orchard freeze (Box Elder, Utah) and wildfire-and-drought event (Beaver, Iron, Juab, Sanpete, Sevier). Utah Farm Bureau is the right channel for documenting compound impacts to USDA. |
FDO 07 — Alfalfa belt convergence: producers themselves are reporting the same geography
| Source / trace | KSL TV reporting from Sanpete and Sevier county farmers (June 2026): fields "looking like late summer" in early June due to irrigation curtailment; producers losing 1–2 cuttings; explicit warnings that dry alfalfa fields are themselves highly ignitable. |
| Implication | Sevier and Sanpete county fire-protection districts should coordinate with Utah Farm Bureau on water-supply continuity for active firefighting in agricultural areas. Producer-side mitigation (controlled burns of stubble where safe, fire breaks around equipment yards, livestock-evacuation routes) deserves immediate technical support. |
FDO 08 — Statewide drought emergency + record-low snowpack
| Source / trace | drought.gov (Utah): 100 % of Utah in drought as of 9 June 2026; 95 % Severe+, 60 % Extreme. Every major basin at record-low April 1 snowpack; ~95 % of state water supply derives from snowpack. Gov. Cox declared statewide drought emergency. |
| Implication | The fire-weather context is structural this year. Even after the named fires are contained, the next 60–90 days remain in extreme fire-weather posture until the North American Monsoon onset relieves conditions in late July / August. |
Adversarial / methodological FDOs
FDO 09 — ENSO baseline correctly aligned but climatological signal in Utah is weak
| Source / trace | Model used El Niño baseline. NOAA CPC June 2026: El Niño present (Niño-3.4 +0.7 °C). Caveat: the El Niño signal in the Intermountain West summer is weak and inconsistent. |
| Implication | The mid-2026 conditions in Utah are best explained by the warmest-winter-on-record + record-low-snowpack chain, not by El Niño specifically. The baseline alignment is correct for the anomaly computation but the climatological prior for Utah summer fire weather is weaker than the same model run in tropical-Andean settings. |
FDO 10 — Area-class absolute totals are not quotable in this run; ratios remain interpretable
| Source / trace | Cropland total 259,910 ha plausible at MODIS resolution but probably under-counts dryland-wheat acreage. Built-up "total" 21.97 M ha ≈ Utah's land area, implausible. |
| Implication | Quote percentages, not absolutes. Cropland 12.35 %, solar 1-of-28, fire-correspondence to named fires (FDO 04, 05) are all valid public-communication claims. |
FDO 11 — North American Monsoon onset is the easing forecast
| Source / trace | NIFC monthly/seasonal outlook + drought.gov 2026 Southwest Monsoon update (18 June 2026): fire potential remains high through July across Utah; easing in August with North American Monsoon onset; CPC predicts above-average monsoon precipitation. |
| Implication | Maximum fire-suppression resource pre-positioning makes sense for the next 4–6 weeks; relief expected from late July onward if the monsoon onset arrives on schedule. The monsoon is the dominant uncertainty in extending the forecast beyond the model's 21-day horizon. |
6. Limitations & caveats
- Cropland classification at MODIS ~500 m under-resolves the smaller specialty-crop pockets in Box Elder and Utah counties. The 12.35 % is a county-and-region-level number; field-scale targeting requires higher-resolution land-cover data.
- GPWv4 vintage 2010–2015 for population. Utah has grown ~25 % since; the absolute count is a lower bound.
- Range and pasture lands are not in the cropland mask but face parallel and arguably greater fire risk. The 12.35 % cropland exposure understates total agricultural-land exposure for Utah.
- Area-class absolute totals are not quotable (FDO 10).
- The ENSO climatological signal in Utah summers is weak (FDO 09).
- WRI GPPD point locations are imprecise; FDO 02 should be ground-truthed against operator records.
- The 6-component hazard coefficients were calibrated for tropical-Andean fire regimes; performance for Intermountain West sage-grassland and pinyon-juniper systems is empirically validated by media triangulation but not formally re-tuned.
7. AI-use disclosure & reflexive memo (JANUS)
LLM assistance. A large language model assisted with structuring sections, drafting the plain-language Simple text of each FDO, executing the media-triangulation web search across Utah Fire Info, Inciweb, SLTrib, KSL, Deseret News, ABC4 Utah, KUTV, Fox13, Cache Valley Daily, Gephardt Daily, Utah Farm Bureau, drought.gov, NRCS, BLM Utah, and NIFC, and weaving findings into the FDO structure. The LLM did not generate the model output, fabricate exposure numbers, or invent the named fires or the orchard freeze damage.
Provenance. Exposure figures read directly from the model's exposure panel. Model code: PROD/src/earth-engine/integrated-multihazard-model-tuned.js (Wildfire Ensemble class, legacy multiplicative sharpening at 0.7 strength). Median media-source search recency: 2 days. ENSO classification: NOAA CPC June 2026.
Reflexive memo. The analyst is Colombian and not a Utah resident. Specific institutional naming (UDAF, Utah Farm Bureau, BLM Utah, NIFC, Utah Division of Emergency Management) is used as appearing in cited sources. Utah-resident Capybara volunteers should validate the agricultural-sector recommendations in §4.5 before any direct dispatch.
Adversarial pass. Five alternatives considered. (1) Beaver County concordance with Cottonwood Fire is coincidence — rejected: model identifies Beaver as brightest cluster from independent EO data before the specific ignition. (2) 12.35 % cropland exposure is inflated by MODIS misclassification — partially accepted; geography is well-established alfalfa territory regardless. (3) April freeze is unrelated to June fires — rejected (FDO 06): both downstream consequences of warmest-winter-on-record. (4) Solar-farm finding misattributed — partially accepted; ground-truth against operator records. (5) El Niño-baselined surface over-predicts in Utah — partially accepted (FDO 09); spatial findings remain valid via ground triangulation, magnitude may be slightly elevated.
