The San Miguel River cuts a deep path through the high plateaus of San Miguel County, framing a landscape defined by its mining and transportation history in the early 1950s. This survey, conducted in conjunction with the United States Atomic Energy Commission, highlights the critical industrial role of settlements like Vanadium and Lime. The transit network of the era is preserved through an Old Railroad Grade that winds toward Vance Junction and Illium, tracing the legacy of narrow-gauge rail that once serviced the local ore deposits.
