Howardsville and the nearby settlement of Middleton sit at the confluence of mountain waters where the Animas River meets tributaries like Cunningham Cr. This 2019 survey documents a landscape defined by high-altitude basins and mining-era nomenclature, such as the Arrastra Basin and Hematite Basin, reflecting a long history of mineral exploration in the San Juan Mountains. The terrain is divided by the Continental Divide, which separates the headwaters of the Rio Grande flowing east from the Animas River drainage flowing west. High alpine features including the Highland Mary Lakes, Silver Lake, and Crystal Lake are scattered among peaks like King Solomon Mtn and Galena Mtn. The map also traces modern recreational routes, most notably the Continental Divide National Scenic Trail, which winds through the San Juan National Forest and Gunnison National Forest.
