This map covers the region of Texas between the Rio Grande at left and east to include Matagorda Bay, Preston and Fort Washita. There is good detail along routes, especially around San Antonio de Bexar, and mostly blank elsewhere. Shows a reconnaissance of 1849 in red and Lt. Whiting's route in blue. It is filled with geographical information, forts, presidios, springs, fords, watering holes and much more. A fascinating and historical map which is mostly uncolored save for fine coloring along the routes.
