The Purgatoire River carves through the landscape of Las Animas County, shaping the life and industry of the Picketwire Valley during the early 1970s. This survey records a transition from traditional livestock and irrigation to industrial extraction, evidenced by the North Fork Aqueduct cutting across the slopes and the Allen Mine (West Portal) near the Middle Fork. Small Hispanic settlements like Vigil and Parras Plaza remain central to the local geography, anchored by cultural landmarks such as the San Isidro Ch and the Vigil Cem.
