1918 Map of Bullis Gap

About this map

Bullis Trail winds through the high desert of the Big Bend region, serving as a primary corridor for movement through the Bullis Gap Range toward the international border. This 1917 survey, published at the end of the First World War, documents a landscape of isolated outposts and vital water sources essential for survival in this arid environment. Small hubs of activity like Kellogg and Espanol House appear alongside livestock-focused sites such as Valdez Goat Camp, illustrating the early ranching and transit patterns near the Rio Grande.
