Cold Boiling Lake Professional Review and Guide
"Cold Boiling Lake is unique in this volcanic park for its subtlety. It lies quietly in its alpine basin, surrounded by a still forest and black-streaked dacite cliffs. Its shores are placid and its waters inviting—you may wonder, as I did, how this seemingly normal tarn could be in any way volcanic. Then, you see them: tiny bubbles gurgling relentlessly among the grasses in the lake before bursting noiselessly on the surface. Caused by the gases escaping Lassen’s turbulent innards, the bubbles are a relatively benign reminder that indeed, you are standing on the slopes of a volcano. Highlights: This easy trek leads to an odd, but lovely, bubbling lake."
