Big springs trail head bye W mountain( Colorado). I did see a box canyon on the topo but I did not head up in to it. There was a lot of cattle grazing in the lower meadows and I was unsure if the elk would stay away from them so I explored up Red dirt creek trying to climb in elevation. It seemed most creek bed up high we’re dry I will have to do some more exploring and see if I can find some secluded springs /seeps
