Here is a nice collection of reports on the Phosphoria formation in Wyoming and Montana, plus a report on coal in Montana, totaling five in all. Altogether there are 144 pages of text here, plus one map in this set. For one low price! From oldest to newest, they are:
USGS Circular 53,
“Coal Resources of Montana.”
Published in 1949. Discusses numerous regions in the state. Some of these areas are historical producers, so I’ll list them here:
Fort Union
Garfield County
Bull Mountain
Great Falls and Lewistown
Bearpaw Mountains
Blackfeet-Valier
Bridger and Silvertip
Stillwater
Red lodge
Electric
Livingston-Trail creek
Lombard
Flathead
USGS Circular 209,
“Stratigraphic Sections of the Phosphoria Formation in Montana, 1947-1948.”
Published in 1953 this 31-page book comes complete with the LARGE FOLDOUT MAP. It discusses the occurrence of this important formation that has been mined for phosphate in many places. Discusses all the members of the formation, not just the phosphate-bearing ones.
USGS Circular 260,
“Stratigraphic Sections of the Phosphoria Formation in Montana, 1948.”
Published in 1953 this 39-page book is much like the other one described above. It discusses the occurrence of this important formation that has been mined for phosphate in many places. Discusses all the members of the formation, not just the phosphate-bearing ones.
USGS Circulars 324 and 325,
“Stratigraphic Sections of the Phosphoria Formation in Wyoming, 1951”
and
“Stratigraphic Sections of the Phosphoria Formation in Wyoming, 1952.”
These were both published in 1954. These short books discuss the features of this widespread and important formation in various areas of Wyoming. These books are 22 and 24 pages long. The Phosphoria formation is probably North America’s largest single resource of phosphorous rock and has been mined at several places for phosphate. It is a regionally extensive Permian formation present in Montana, Idaho and Wyoming.

SONLY ONE AVAILABLE!! HOT ITEM WHEN I CAN GET ONE!!
This is USGS Bulletin 1042-R,
Geology of the Ord Mine, Mazatzal Mountains Quicksilver District, Arizona.
Published in 1958, there can’t be many of these around. This publication consists of the 14-page book and all three of the original maps. The map of the area clearly shows the locations of all the surface workings, shafts and pits. The two other maps are of the underground workings. Very cool!
This is an interesting area with geology that is different from the typical hot springs type of mercury deposit. This site actually has native mercury, which is a pretty rare thing, and a bunch of other minerals as well. Look at this list, drawn straight from this publication:
Barite
Chalcocite
Chalcopyrite
Cinnabar
Hematite
'Limonite'
Mercury
Pyrite
'Sericite'
Siderite var: Magnesian Siderite
Tennantite var: Mercurian Tennantite
This area is not very far from a road and would probably not be hard to reach to explore. All in all this is a very interesting, detailed and scarce report on a little known mine and would make a great collecting guide.
