Prentice found extensive shelters with pictographs on the sandstone cliffs east of Hidden Lake. One was a panel of multiple sacred images painted apparently by the Plains-living Jicarilla Apaches. On August 2, 1933, Prentice sent a letter describing the pictograph to the Museum of New Mexico, and Stanley Stubbs sent Santa Fe artist Louie Ewing to make this silkscreen rendering of the panel.
