Comments on the location information

  • A.B. Wilson unable to verify location based on references. The only place I found Holbrook mentioned is in Bull. 1261F, p. 113. It is not shown on any of the plates though is considered part of "Group J" on fig. 17, p. 110. It is possible that this site could be either samples 142-144 or 145-149 on MLA 19-85, pl. 2. The location is probably accurate within about 2 km.
