When I was a boy I dreamed of exploring caves. We’re lucky to live in a place where I can take our boys to such things. This is at some random cliffside north of Los Alamos. We drove way down Rendija to the power station, took a left at Guaje canyon, then immediate right up a 4WD road to climb back up onto the mesa, then explored that whole area. The boys saw a cave along the hillside so we walked out to explore.
