Summary

Overturned and broken head of the pitted reef shown in Bradley photo 165, this shows near the hammer head a hole that contained the nucleus. It also shows the eccentric growth layers, which may be annual, and near the top of head (lower edge of photograph near the center) several open pit tubes. These are indistinct, partly because they are weathered and partly also because they are somewhat overgrown with algal deposits as the reef formed. Moffat County, Colorado. August 2, 1925. Plate 39-A in U.S. Geological Survey. Professional paper 154. 1929.
