Colorado's Infrastructure Faces Distinct Geohazard Risk
Colorado's Rocky Mountains generate some of the most persistent rockfall in the country along the I-70 mountain corridor, where freeze-thaw cycling and seismic-free but geologically active terrain combine to shed rock onto one of the nation's busiest interstate highways. On the Front Range, a completely different hazard dominates: bentonite-rich expansive clay beneath Denver metro development swells and shrinks with seasonal moisture, cracking foundations and buckling pavement in a pattern unrelated to the mountain corridor's rockfall risk.
This pattern is consistent with the broader Rockfall Hazards challenges GSI addresses statewide.
