It is a huge boulder of reddish sandstone, two-thirds the way up a steep hill on the north bank of the Marias River, about five miles from Fort Conrad. Formerly, this rock rested on the top of the bluff, but, as the soil about it is worn away by the wind and the rain, it is slowly moving down the hill. The Indians believe it to be alive, and make presents to it. When I first visited it, the ground about it was strewn with decaying remnants of offerings that had been made to it in the past. Among these I noticed, besides fragments of clothing, eagle feathers, a steel finger ring, brass ear-rings, and a little bottle made of two copper cartridge cases.

Perhaps the oldest specimens, probably dating from the 1860's, are two described by Karl Schmitt (1950). These vessels are similar to McIntosh Roughened in most respects, being almost identical in the vessel shape (Fig. 24, H–I), rim notches, and surface finish. They differ, however, in having crushed sandstone instead of fine grit or quartz tempering (Goggin1964:204). ANNOTATED BIBLIOGRAPHY Goggin, John M. 1964 Seminole Pottery.

This book opens with a series of English translations of Blackfoot texts, divided by Grinnell into adventure stories, origin myths, and accounts of the travels and doings of the culture hero, Na'pi ("Old Man"). This section is followed by an ethnographic sketch incorporating material on all three Blackfoot subdivisions (Sík-si 'kau, Kaínah or Blood, and Pikuni or Piegan), that includes data on daily life, social organization, hunting, warfare, religion and ritual, and curing.
