Verde Hot Spring along the Verde River, southeast of Camp Verde, Arizona. Hot springs throughout Arizona were sampled for isotope and geochemistry analysis, excluding Verde Hot Spring (pictured) which was attempted but inaccessible due to high water flow, to assess the source of thermal groundwater exhibiting unusually high temperature anomalies. The Camp Verde hot springs burble away near the remnants of an old hotel that burnt down in 1962. It was apparently a swank spot in the Jazz Age, but rumors that Al Capone used it as an occasional hideaway are pure fiction.
