## About Green River Soda Spring

Green River Soda Spring is a mineral spring in Lewis County, Washington, a dozen miles or so from Morton. The name says soda spring, the old term for naturally carbonated water. No chemistry sits in the record to confirm it. What is on file is a temperature in the high eighties, warm to the touch and too cool for a real hot soak, and a location a stone's throw from pavement. Ownership and access are blank.

This one is close to the road, a little over a hundred feet by the record, though the road itself goes unnamed in the record. Low elevation for the Cascade foothills. Wet country, with seventy-five inches of rain a year and a similar figure for snow, so the cold months bring real accumulation even this low down.

Winter is the season the record prefers. Iron Creek Campground, close to fourteen miles off, is the camping option on record. The water is only warm, so there is no burn risk, and there is also no mention of a pool, a fee, an owner, or permission to visit. Treat it as a dot on the map until you can confirm what is there.
