<div><br></div> There are actually at least four more-or-less related vents above Spiteful, but two of them are usually buried.<div><br></div><div> The first is the familiar "Spiteful's Sput," a slit-like vent located in Spiteful's crater on a shelf right at or just above the water line, that ranges from continuous blurbling to large, angled jets that land well clear of the crater. It's activity is pretty consistent and continuous any given year--when it's active, the only times it stops are after euptions of Spiteful (stops entirely) or Fan and Mortar (sometimes stops, sometimes slows down to strong overflow, sometimes keeps going, possibly related to).</div> <div><br></div><div> To the left of and above the main sput (viewed from the old road), there's a crack that more or less lines up with the fissue Spiteful and Fan's vents are on. This crack is also sometimes active as a spouter, albeit a much smaller one. When active, water is visible splashing in and just above the crack. It's visible, but not erupting, just below and left of center in this photo: <a href="http://www.flickr.com/photos/12205793@N04/5119345811/lightbox/" target="_blank">http://www.flickr.com/photos/12205793@N04/5119345811/lightbox/</a> </div><div><br></div><div><div> Next, just up from the crack and basically in line with it, there's a vent that is almost always buried. It was cleared in the mid 1990s by NPS volunteers and took over much of the function of the main sput. The crack vent was active along with it, and as I recall, the main sput was reduced to a strong, bulging overflow. This vent was reburied over the course of a year or two and to my knowledge, no effort has been made to clear it since.</div> <div><br></div><div> The last one is probably not directly related to the other three.<br></div><div><br></div><div> It's well known that, when the road was built through the Upper Geyser Basin, a spring/geyser above Spiteful at the edge of the road was capped with stone and concrete and its output diverted through a tile-lined culvert to an outlet downslope from Spiteful. The culvert was known to discharge a flood of output during eruptions of Fan and Mortar in the '80s and '90s, so it was often referred to as Fan's "Tile Vent." One summer in the late 1990s, a spot in the gravel in front of the concrete cap started steaming, sputtering, and periodically filling with water. We all assumed at the time that it was a break in the pipe or some other expression of the buried spring. The activity did not persist.</div> <div><br></div><div> As for whether they're separate geysers... I'd say no, not any more that the cone sputterers on Daisy are separate geysers. When Spiteful is full, the sput is in eruption--from whichever vent is dominant. When Spiteful drains after an eruption, the sput quits. It's a high-water-level vent of Spiteful that functions as a perpetual spouter when active.</div> <div><br></div><div>David Schwarz</div> <br><div class="gmail_quote">On Sat, Feb 11, 2012 at 1:11 AM, JEFFREY CROSS <span dir="ltr"><<a href="mailto:jeff.cross@utah.edu" target="_blank">jeff.cross@utah.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> A question for all:<br> <br> Is the small vent at the uphill edge of Spiteful Geyser's crater an independent geyser?<br> <br> Also, I recall that a second vent existed here.
