As I work through photos taken this year in Yellowstone, I found a couple of areas near Doublet Pool that I’ve been watching over the years. On our last trip in July, it seemed like it had changed. So digging back through photos and found a comparison. Not only has this ‘small stuff’ UTF (Unnamed Thermal Feature) changed, but it seems that Doublet Pool is overflowing more than it has in the past. I still have more photos to dig through from last year to see if I took one then, but at least in May of this year, the area looked basically the same as in these photos. I’m wondering if this is connected to Doublet Pool – watching it for a bit while waiting for thumps from Doublet is on my ‘to do’ list for this next trip. If you happen to already know or will find out before our next trip, please leave a comment to let everyone know.

The other change noticed was right next to the sign for Doublet Pool – it’s what my husband and I have referred to as “Doublet’s Triplet” for lack of a better name. During our May trip, it had turned into more with a new hole up on the upper left – but little change seemed to have happened on our July trip. But – just another spot to watch.
