English: Minute Geyser, northern Back Basin, southwest-central Norris Geyser Basin, Yellowstone Hotspot, northwestern Wyoming, USA on 9 August 2011. (looking ~SW)

This is no longer a “natural” feature. Morons and boneheads over the decades have significantly vandalized this geyser. It formerly had very frequent eruptions (hence the name). Anti-nature jerks have thrown innumerable rocks into Minute Geyser’s vent basin (compare this with the thousands of coins and other trash thrown into Morning Glory Pool in Yellowstone’s Upper Geyser Basin). Some of these rocks were removed in the 1930s, but more rocks were later thrown in. The vent is basically sealed up now - geyserite has cemented the rocks together.

Minute Geyser has two vents - the larger main vent has been wrecked. The smaller vent’s activity includes small to medium-sized geyser eruptions. In the early 20th century, some Minute Geyser eruptions reached about 80 feet high.

Water here is almost neutral to very slightly alkaline and is hot to very hot.
