A free, visitor-built rock-and-cement soaking tub perched on a low rise in the Long Valley Caldera east of Mammoth Lakes, with open views of the Eastern Sierra. Fed by a local geothermal spring and reached by a short walk from Benton Crossing Road parking, it is one of the most accessible public soaks in the Mono geothermal cluster—distinct from the Whitmore community pool and the closed Hot Creek river soaks.
