Along the St Vrain Greenway in Longmont, there’s a stretch called Lykins Gulch, that I pass thru often on bike rides.
I didn’t know what a gulch really was, so I looked it up on Wikipedia:
“A gulch is a deep V-shaped valley formed by erosion. It may contain a small stream or dry creek bed and is usually larger in size than a gully. Sudden intense rainfall upstream may produce flash floods in the bed of the gulch.”
Not sure if Lykins Gulch fits that description. There are no valleys that I can see there, or in the surrounding landscape.
