Burned hillsides can’t soak up heavy rain, so mud and debris can rush downhill with little warning.

Landslide-prone ground
USGS maps about 59% of Salt Lake County as ground susceptible to landslides. Its national inventory lists 436 documented landslides in the county.
This is a county-wide figure, not a rating for your spot. Steep slopes, road cuts and burned hillsides above you matter most in heavy rain.
From the USGS U.S. Landslide Inventory and Susceptibility data release (2024). Susceptible ground is terrain steep and high enough for landslides like those mapped in similar places. The inventory counts only slides someone mapped, and some states map few, so a low count doesn’t mean the ground is stable.
