Publisher Information:
Washington: Government Printing Office, 1850.

31st Congress, 1st Session, Senate Ex. Doc. No. 47. 127, 37, 10 plates 3 folding maps. Disbound government document. Pages browned, one plate split completely at fold with no loss. Rebound in 1/4 leather. Tyson based this memoir on his personal observations made during a four month visit in the summer and fall of 1849. Wheat says that this is, "probably the earliest work of a true scientific research to emerge from the Gold Rush. Its author was a gifted scientist whose pioneering effort was of considerable value." The maps are important. They include The Sacramento Valley from the American River to Butte Creek, Geological Reconnaisances in California, and Sketch of the Route of Capt. Warner's Exploring Party. Additionally, some of the plates are actually small maps including Topographical Sketch of the Los Angeles Plains, and Survey of Public Lands in the Gold Region. Most of the plates are geologic sections of which are, again according to Wheat, of no little importance in the history of geological research in Western North America.
