This basin overlooks the vast Yellowstone Lake, very quiet at this moment. All this hot springs pours an average of 3.100 gallons (11,700 liters) into the lake, but even in summer lake's average temperature is 45°F (7°C). We are a few meters away from the Fishing Cone, this time underwater of the lake.
