From the ancient sedimentary formations in the north through the overthrust belt in the southeast, Idaho's rocks are as interesting as rocks come. The authors know these rocks well through their years of research in Idaho, which led to their theory explaining the flood basalts of the Columbia Plateau and the hotspot track of the Snake River Plain as the results of a giant meteorite impact that happened about 17 million years ago.
The famous Estwing Geo/Paleo Pick GP100 has made a grand reentry after being out of production for several years. The handle has been beefed up to make the unit even stronger. It is 25 inches long with a total weight of 3 pounds. Painted steel with a soft vinyl grip. The light weight but great strength of this makes it a great field tool for any geologist or rockhound.
Not only is this a great digging tool but I use mine to help me navigate the steep slopes of mine tailings. Jab the tip in and pull yourself up then use the hoe end to cut a quick shelf to work from.
Montana's geologic history includes a long succession of disturbances that changed the rocks, then changed many of them again. Unraveling these events reveals a geologically quiet continent that got scrambled in a long and grinding collision with the Pacific crustal plate. Through detailed geologic maps and lively text, Roadside Geology of Montana deciphers the complicated rock record and uncovers each layer of Big Sky Country.
