I'm looking for localities to collect shale or slate, preferably gray, not far off the interstate 15 or interstate 70 corridor anywhere in California, Nevada, Utah, or Colorado.

Are you looking for any particular age, color, fossil?

How far is "not far" off I-15 or I-70?

I know I am in my own little world, but everyone knows me here.

STEVE At the Indianapolis Harding Street Quarry, gray shale is the overburden pushed aside to get at the underlying limestone which is used to scrub coal at the adjacent electric utility. Parenthetically, in the shale are the pyrite nodules that I have pictured in other threads.

The quarry is adjacent to I 465 with direct I 70 connections to both the East and West around the city. The shale is sooooo abundant, just asking at the office or looking in the visitor parking lot will get you some representative samples. CHEERS............BOB

Rick, The materials are for an art project, with specific color and mechanical property needs. I'll need to access the material at the locality to determine if it's suitable. "Close" means maybe ten miles or less. The collecting stop is intended to be a brief side-trip on our way from Los Angeles to Denver (or vice-versa), and not a day trip by itself.

Bob, When I lived in Indiana I was pretty sure that Indianapolis is not between Los Angeles and Denver. But then again I was just a naive graduate student at the time, my brains addled by Indiana humidity and winter, so perhaps I was wrong.

Not sure if it will meet your criteria, but the Green River Shale is exposed minutes north of the I-70 in the scenic Book Cliffs in the vicinity of Grand Junction, Colorado. A bonus is nice barite crystals at this locality within the shale.

Jim, that's a good suggestion. Do you have more specific details?
