[Geysers] What did I see?

[Randal H]

Okay, longtime lurker, first-time poster, yadda yadda yadda...be gentle with me :)

I was in the Upper Geyser Basin on Sunday (May 16) and was on Geyser Hill near the Lion complex as it had given a few 2-4 foot splashes and I was hoping that perhaps an eruption was near (it wasn't, and as best I know, never did, during my time there). 

Around 12:50 p.m., I decided to give up the wait and attempt to catch up to my wife who was down basin, but first I wanted to go peek in on Depression one last time. As I made my way down (probably 1/3 of the way from Lion to Depression) I noticed, looking in the gap between the Lower Ham store and the service station, behind said buildings, the tail end of a burst (i.e.-I have no clue what, if anything, I missed before my attention was drawn) that appeared to reach about tree-top level (so I'll guesstimate 15-25 feet), there was a second burst roughly 1/2 to 2/3 the height of the first observed one, then nothing more. From the vantage point I had, the activity was just to the left of the left edge of the service station. I have no idea depth-wise where the burst may have originated from with regard to "closer to the station" vs. "closer to the tree-line behind"

I've made numerous trips to the UGB, spending most of my Thursday, Saturday and Sundays in the park, usually two or three of which are largely in the geyser basins. I can't recall ever seeing anything erupting from that location, be it last summer or during my previous years in the Yellowstone area. While I own various incarnations of Geysers of Yellowstone, I'm having a hard time getting my bearings on the maps and descriptions for that area. None of the little numbered dots that look "in the area"  seem to parallel, even roughly, what I saw. 

So, I'm turning to the masses...any clue what it may have been? Thanks in advance for helping put my curiosity to rest.
