Simcoe Soda Springs is on the Yakama Nation Reservation in Yakima County, Washington, about twenty miles from Tieton. The water reading is at the bottom edge of soaking warm, around ninety. Access is recorded as unknown, and the land is tribal, which means permission is a matter for the Yakama Nation.

Location

Some four hundred feet off an unnamed road, per the record. Elevation around twenty-four hundred feet. Fairly dry: thirty inches or so of rain, though snowfall on file is close to a hundred inches. Tribal land designation.

Do not go without contacting the Yakama Nation about access; the record lists it as unknown and the land is reservation land. For camping, the record points to the South Fork group site in the Wenatchee National Forest, roughly fourteen miles away. Winter is the season on file. The water is too cool to burn anyone.

Heat Below
74 milliwatts per square meter of heat flow

That's close to the US average of 65. It's higher than at 9% of the springs on this site.

Heat flow measures the warmth working its way up through the ground from deep inside the earth. Where it runs high, rain and snowmelt that seep down through cracks in the rock come back up hot.
