Glenwood Springs

Every large fire

1. Large fires mapped by the Monitoring Trends in Burn Severity program since 1984: 1,000 acres or more in the West, 500 or more in the East. Prescribed burns are excluded. Acres here are the part of each perimeter inside this place.

Monitoring Trends in Burn Severity (USGS and U.S. Forest Service), 1984 to 2026.

Smoke overhead

1. A smoke day is a date on which a smoke plume traced by NOAA Hazard Mapping System analysts from satellite imagery covered this place's point (the county's population centre or the city centre). Counts here are of medium or heavy smoke. Since 2018 analysts have often drawn light smoke as one area over most of the continent, so light-smoke counts are not comparable from year to year. The plumes show smoke anywhere in the air above, not air quality at the ground, and smoke hidden by cloud is missed.

River crests

River gauges in Garfield County, the county that contains Glenwood Springs.

River gauges

1. Crests are the highest and the recent crests the National Weather Service lists for each river gauge in the county that has a flood stage, not every flood. Flood categories use each gauge's current flood stages; crests from before levees, dams or channel changes may not be comparable. Crests measured on an old datum are left out of the rankings.

The drought index is for Garfield County, the county that contains Glenwood Springs.

1. The Palmer Drought Severity Index is computed by NOAA each month from the county's average temperature and precipitation, relative to the county's own climate. Zero is normal; -3 or lower is severe drought and -4 or lower extreme drought. It describes the long-term balance of moisture, not water supply or crop losses.

Every earthquake of magnitude 4 or more within 50 miles

1. Earthquakes of magnitude 2.5 or more in the USGS Comprehensive Catalog since 1900. Within 50 miles means the epicentre lies within 50 miles of the city centre.
2. Small earthquakes were under-recorded before the modern seismic networks of the 1970s and are still missed in remote areas, so early decades read low. Magnitudes are as the catalogue reports them and mix scales (moment, local and body-wave).

Volcanoes within 100 miles

1. U.S. volcanoes within 100 miles, from the USGS Volcano Hazards Program. The threat category is the USGS 2018 National Volcanic Threat Assessment, which ranks volcanoes by how hazardous their past eruptions were and how many people and how much infrastructure lie near them. It is not a forecast of eruption.

Mapped landslides

Landslides mapped in Garfield County.

Mapped by CO GS (2,353), USGS Post-Fire Debris Flows (17), NASA (10), USGS Conterminous (2), UT GRC (1).

1. Landslides mapped in the USGS compilation of landslide inventories across the United States (version 3.0, 2025), rated probable or better. The compilation joins inventories made by federal and state agencies for different purposes and areas, so the number mapped in a county reflects how closely it has been surveyed as much as how often its slopes fail. An area with few records may simply not have been mapped. Deaths are as recorded in the inventories; a slide listed in two inventories is counted once.

1. Jul 29, 2021Debris Flow$125 million
   National Weather Service narrative

   Major flash flooding and debris flows occurred throughout Glenwood Canyon from the Grizzly Creek Fire burn scar as a result of significant rainfall from showers and thunderstorms. Multiple mudslides were reported by the Colorado Department of Transportation (CDOT). Numerous vehicles were trapped between slides for several hours. Rainfall rates in excess of 4 inches/hour were estimated with storms. Remote gauges recorded between 1 and 2 inches in less than an hour along the south and east sides of the burn scar. CDOT reported damage to the structure of Interstate 70 which remained closed for over two weeks due to cleanup operations and surveys.

2. Jul 31, 2021Debris Flow$25.0 million
   National Weather Service narrative

   Multiple debris flows occurred along Interstate 70 within the Grizzly Creek Fire burn scar between mile marker 123 and Hanging Lake Tunnel. Colorado Department of Transportation (CDOT) described the damage from the new flows as extreme. The new debris piles were around 17 feet tall over the roadway and house-sized boulders fell as well. Hanging Lake trail received considerable damage. At least seven bridges were either destroyed, washed downstream or otherwise severely damaged. National Forest officials say it will be at least late-season 2022 before the trail can be reopened.

3. Jul 1, 2023Wildfire, Debeque To Silt Corridor$4.0 million
   National Weather Service narrative

   The Spring Creek Fire started in late June 5 miles southwest of Parachute, and grew to 3286 acres before it was finally contained in early September. The cause of the fire is unknown.

7. Aug 1, 2018Wildfire, Gore And Elk Mountains/Central Mountain Valleys$3.5 million
   National Weather Service narrative

   The Lake Christine Fire began in early July from human causes, allegedly from tracer rounds fired at the Basalt Gun Range about a mile northwest of Basalt. Lack of rainfall and gusty winds allowed the fire to grow to a total of 12,588 acres before it was finally contained in the beginning of October. Periodic road closures were in effect as well as closed access in the White River National Forest. Numerous neighborhoods were evacuated. The fire destroyed three homes, a barn and an outbuilding. The three homes had a combined value of $2.65 million.

   The Coal Seam fire which began in early June (see the June 2002 Storm Data publication) was contained on July 10th. The fire destroyed 29 residences and 14 other buildings. Nearly 3000 people were evacuated from that area. The cost of fighting the fire was in excess of 7 million dollars.
