Simcoe Soda Springs
Simcoe Soda Springs flows at 90 degrees Fahrenheit on Yakama Nation Reservation tribal land in Yakima County near Tieton, with unknown public access status reflecting the reservation's sovereign jurisdiction. The spring sits at 2,415 feet elevation 135.6 meters from the nearest access point, where it would require a short walk if access were available. Water flows 41.6 degrees above ambient temperature in this eastern Cascade location.
The spring occupies the eastern slope of the Cascade Range at 2,415 feet where the forest transitions toward the drier interior plateau country. Annual precipitation of 30.6 inches with 95.7 inches of snow reflects the rain shadow effect, with less moisture than the west slope but more than the Columbia Basin lowlands. Average temperatures of 48.4 degrees create a climate with warm summers and moderately cold winters. The Yakama Nation Reservation encompasses this area, with the spring likely situated in terrain showing mixed ponderosa pine and Douglas fir forest. The 'Soda Springs' designation indicates mineralized, carbonated water rather than the sulfurous chemistry typical of many volcanic hot springs.
The spring's name references both its location on the Yakama Nation's Simcoe Mountain area and its carbonated 'soda' character. The Yakama people have utilized this spring for generations, with the thermal feature holding cultural significance within tribal territory. Public access status remains unknown, requiring permission from the Yakama Nation for any visits, respecting tribal sovereignty over reservation lands.
Do not attempt to visit without explicit permission from the Yakama Nation, as this spring sits on tribal land with no documented public access. The reservation's boundaries and access policies are sovereign matters under tribal jurisdiction. If permission were granted, the short walk from the access point would be straightforward during spring through fall, with winter snow potentially complicating approach. South Fork Group Site 23.1 kilometers away on Wenatchee National Forest land provides the nearest reservable camping outside tribal boundaries.
