Be careful whenever thinking of applying a name to something (as Whittlesey will tell you -- there might already be a prior name, even if "forgotten"). I don't know for certain if this is correct or not -- I don't think we'll ever know -- but my belief is that the "large, multi-vented spring" described here is the feature that was called Azure Lake way back in the 1800s. I have that in the new edition of "the" book. Azure Lake definitely was NOT today's Azure Spring. As for info about the effects of the 1959 earthquake, Marler's Inventory, of course. Some info in my book, yes. But look for USGS Professional Paper 435, in which Marler's article was titled "Effects of the Hebgen Lake Earthquake........"

Prior to this year it was always the largest hot spring in the area, with runoff flowing off of two sides, towards "Thermopod Geyser" and also towards Fortress. As of July 24, water was sitting 4 or 5 feet down within its two largest vents, one of the smaller vents on the north side was a perpetual spouter from a low pool, and the rest of the vents were essentially dry. **************Looking for a car that's sporty, fun and fits in your budget?
