Aurum Geyser is a small but pretty feature, named on account of the golden staining (due to iron oxide) around the vent and the adjacent pour-over pool. The spring has been erupting regularly following a small earthquake in 1983, sending water 15 to 30 feet high at intervals between 3 and over 10 hours, this period seemingly affected by the moisture content of the surroundings. Activity lasts for just over a minute, and is very occasionally followed by a second, smaller eruption up to ten minutes later. When not erupting the vent is filled by bubbling water, rising just a few inches. The vent is angled, and the geyser lies close enough to the path to briefly envelop it with steam.
