Olney was the only publisher to include this map and it is not seen often. It shows the western territories lying north of New Mexico. Included are Oregon, Utah and Nebraska. Nebraska is the largest and includes all of the plains from the Arkansas River to Canada. Oregon includes all of present day Washington and extends to the continental divide and Utah from California to the divide. Some trails and the towns and forts of the region are shown.
Condition is good with some soiling and light scuffy. Image size is approximately 11 x 17.75
