I first heard about this site from a friend in the US Forest Service, and finally got an opportunity to visit.   My first visit was on a sunny day, with contrasty lighting, so I later returned on an overcast day with more even lighting. 1 - First visit, December 2019:

This quarry consists of a single huge soapstone boulder with multiple bowl preforms and extraction scars.

We saw a few spots where pieces had been sawed off this boulder long ago.

2 - A return visit with Alan C., December 2019:

Alan at the boulder We counted a total of 38 bowl preforms and / or bowl removal scars on this boulder, with more likely hidden under grade.

This preform is unusually small, no more than 8 inches in diameter.
