What is the san luis river listed on that 1894 map? did people just not know anything about geography back then? Or is it supposed to be a below-ground river? Without severe geologic changes in the last 120 years, it seems unlikely for a river to be flowing out of a closed basin like that!

San Luis Creek flow south into a closed basin (the northern half of the San Luis valley). Due to the porous nature of the ground and the dry climate, the water flows into the ground.
