Mud season in the foothills
Salt Lake City Public Lands describes two mud seasons, typically spring and late fall. Snow melts into the dirt, nights freeze the top layer, and afternoons thaw it again. A trail that is firm at 8am can be soft by noon. Read the freeze-thaw guide before planning a winter ride in Corner Canyon or the other foothill networks.
The city notes that every wheel rut can harden into a hole that holds water or sends it off the trail. That is why riding soft trails causes damage that lasts well past the wet spell.
What affects drying time
Sun or shade
South-facing trails get more sun and are more likely to be dry than north-facing ones. A shaded north slope can stay frozen or muddy for days. See how shade and sun affect drying.
Elevation
The tracked trails here run from about 1480 m to 2669 m. Higher canyon trails such as Wasatch Crest can stay snowed in long after the valley foothills are rideable.
Time of day
Frozen ground can feel solid early and turn to mud as it thaws. Plan around the thaw, not just the last storm.
Before you ride
For Corner Canyon, the Corner Canyon Trails Foundation conditions page links Draper's trail conditions map. Respect any closure you find there. For other networks, check the land manager's notices before you go.
If you meet a short puddle, Salt Lake City Public Lands asks riders to go straight through it. Going around widens the trail. If the ground holds tire prints or mud sticks to your wheels, turn around and come back later.
Loam estimates conditions from recent weather, soil, terrain, and tree cover. Use the network pages below to check the latest estimate, then use the trailhead firmness check when you arrive.
Salt Lake City trail conditions
Corner Canyon and the west-side canyons are lower foothill riding. Mill Creek, Bobsled, and Wasatch Crest sit higher in the Wasatch and open later. See every tracked network on the Salt Lake City conditions page.

Sources and method
Loam estimates conditions from weather, soil, and terrain. It does not measure the trail surface directly or override an official closure. Read how the estimate works and see the published checks and their limits.
- USDA NRCS: Hydrologic Soil Groups, soil infiltration and runoff.
- USGS: Infiltration and the Water Cycle, saturation, land cover, and slope.
These references explain physical processes, not the accuracy of Loam's predictions.
