Peter W requested some more mound info. I started looking for mound photos in my “field book,” sketchpads with photos, drawings and notes of various sorts.I guess this fits a category; stones on stone (in this case a boulder).
The boulder is low and flat and buried partially so I put dotted lines in below.
There is a fire starter base stone in the foreground with pits in it from use, and a clam shell filled with juniper bark tinder, next to my replica ‘pure’ fire starter. Above it is the Deer Head Stone, another clan shell filled with tobacco next to it resting on a stone with a little recess pecked into it to hold the shell.
