I observed these springs two years ago (2010) for around 45 minutes or so. They are cyclic, though I didn't write down any specific data on them. One tiny spring is always bubbling, but the bubbles increase and decrease about every five to seven minutes. It has built up small terraces, not as high or distinctive as the ones near Ohanapecosh Campground, but the Longmire Springs also seep a lot less water, too. I did not see cyclic activities in Iron Mike or any other springs in the area. Here is a photo of the tiny bubbling spring taken July 25, 2010.

I've done some digging and the most information I can find on the springs seems to come from a single website that states that they go through temperature variations from 77-89 degrees F, and that surprisingly they have traces of travertine in them. But can anyone confirm or support this observation that they may have some periodic bubbling? As a Washingtonian I am curious to see if we actually have anything interesting happening with our meager thermal springs. > > Micah Kipple > > Volcanoes are God's Fireworks > _______________________________________________ > Geysers mailing list > Geysers at lists.wallawalla.edu >
