Berwind Canyon Coal slag

This outcrop is located north of Trinidad on County Rd 40.2, a few miles west of the site of the Ludlow Massacre. This coal slag most likely dates back to the early 1900s.

We are at the Eastern edge of the Raton Basin. The top of the slag points toward the lowermost coal in the Vermejo Formation, situated close to the top of the Trinidad Sandstone. The Trinidad Sandstone is prominent just to the left/west of the slag. The bright red surface on the coal slag is the result of in-situ burning of the impurities associated with the coal.
