A Supplicator or Praying figure in San Diego?? Are there other such Pictographs or Petroglyphs in San Diego or Imperial Counties?

This faint pictograph was in a series of shelters at ground level in very east San Diego County.  It was facing east near the entrance to the shelter.  The shelter entrance was blocked by vegetation.  Interestingly, far back in the maze of shelters is a black anthropomorph on the ceiling.  It was a more typical limbs spread pose, in a room that would receive setting Sun exposure.  That room did contain a prayer stick and some quartz crystals.  The photos include how the pictograph appears without any processing and after digital enhancement including D-stretch.

 

 

 

 

 

While similar to Supplicator figures in Utah [ie, Black Dragon Canyon in Utah's San Rafael Swell], the meaning of such a figure in Kumeyaay culture may be different.  Still, its a motif I have not seen locally.  Would appreciate any feedback from the members on their experiences or thoughts.  Are there other examples in Southern California?
