range of the San Miguel as well as the Sneffles group is trach-

Miguel Canon I had one of the grandest and most enchanting land¬ 
scapes possible. The subject is worthy of the brush of Church 
or Moran (see large sketch book). Camped on a small branch of 
the San Miguel near the Uncompaglere divide. 
Sept. 24th: Uncompaglere. Crossed over to South or Dal-

capped with Ho.ljvariegated marls come beneath. There has been 
a fault along the line of the creek, as on the east side the 
shales extend down to the creek bed. The dip is to the west and 
the fault has been pretty uniform - say ten miles long and having 
a displacement not above 600 feet. The trail to the agency passes

passes to the north and is in shale for five miles. An inter¬

ITo.l; got a specimen fror-iMr., Bond. He says the seam is four or 
five feet thick but not solid or regular. Got also a .specimen
