This is local in Santa Fe (Arroyo Chamiso bike trail I think near Chavez
center). Non-flash-flood sandy base is normally flat, about 2 pct grade
maybe 4-5 feet below trail. What is the frequency and how does this
occur? Why is this happening next to the path and not out in the middle of
the arroyo?
Solitons? Skipping stones? What?
We live here; we should know this stuff.
