Feb 23-1924. Saturday, Tucson. With Storganw and his students went out to Prohaer de Caleria about 18 miles N. W. of Tucson. Was there twice be- fore. About the morning climbing around the mountain with the basal gneiss G. guartzite, some hundreds of feet thick, Wanted to make sure that the beds had slumped during their deposition. There can be no doubt about it at all. The slumping is in the laminated beds, either in connec- tion with the conglomerate or without such. The slumping is very local and of varying intensity. In places, it is also brecciated the pieces being very angular. In other places there are local foresetting, but as a rule there is no marked bedding. Some trails are but seldom seen. The conglomerate is of the Archeozoic schist telar with some granite pebbles. There are rein quartz pebbles, but no Proterozoic guartzite pebbles.
