The stark geometry of the Crooked Creek Dam intake tower rises from a turquoise reservoir in this vivid chrome-era view — the concrete monolith anchored to a low highway bridge, rolling green Pennsylvania hills stretching to the horizon behind a red farmhouse, and a busy picnic and swimming beach visible through the tree line at right, alive with tiny figures on a summer afternoon. Crooked Creek Lake, a U.S. Army Corps of Engineers flood-control project completed in 1940, lies just south of Ford City along Route 66 in Armstrong County — the same landscape coal and glass industries once defined — and by the postcard era had become a beloved regional recreation spot for families from Kittanning, Leechburg, Vandergrift, and Apollo. The Ektachrome photograph by Richard C. Miller renders the water an almost Caribbean blue, a color-saturated optimism typical of mid-century American scenic cards.
