merge with Bright Angel Shale
editUSGS doesn't appear to support use of "Bright Angel Formation." USGS does, however, appear to support "Bright Angel Shale" of Tonto Group (AZ*), This article describes the Bright Angel Shale as a member of the Tonto Group (the unit in Arizona). Bright Angel Formation has description being in Arizona. Recommend merging the Formation article into this, the Shale article. See https://ngmdb.usgs.gov/Geolex/Units/BrightAngel_4814.html.
