Hot Springs Near Hot Springs Cove
This companion spring at Hot Springs Cove reaches 158°F with identical geochemical signature to the nearby 192°F feature, suggesting they tap the same deep thermal reservoir at different temperatures. The 116.9°F differential above ambient demonstrates substantial geothermal flux.
Another thermal outlet at Hot Springs Cove emerges at 100 feet elevation with the same coastal setting as its hotter neighbor. The identical mineral composition—1,300 mg/L chloride, 650 mg/L sodium, 180 mg/L calcium—indicates shared deep geothermal sources feeding multiple surface vents.
The temperature difference between these two closely-spaced springs despite identical chemistry reveals how shallow subsurface cooling affects water temperature. Both represent the same ancient geothermal system, cooled variously during ascent through different pathways or depths.
Backcountry access by boat from Unalaska represents the only practical approach; no roads within 28 miles. Site experiences intense maritime conditions with over 140 inches combined annual precipitation and snow. Extreme weather exposure demands careful planning and experience.
