[Geysers] UGB north map

[David Schwarz]

I'd think that the amount of detail to include in the maps depends on the
purpose and target audience.  If the purpose is to maintain a record, then
everything should be on it, linked, if possible, to copious information.  On
the other hand, If the target audience is visitors or prospective visitors,
then show them the most prominent, visually interesting features, with
informative but easily digestible descriptions.

As far as showing features that are no longer active, there are several
levels of "no longer active."  Features that don't put out water anymore but
still have an intact vent could very well reactivate at some point.  Daisy's
Thief, for example, has been quiet for decades, but it's still there.  I'd
be surprised if we've seen the last of it.  Not that I'd put it on a tourist
map, but on a reference map, absolutely.

Features that have been so thoroughly buried that they can no longer be
found probably still ought to go on a reference map, just because we've
often seen that new features tend to break out at or near the site of a
buried feature.  The "Sput" geysers broke out near the site of North and
East Triplets, for example.  Phoenix Geyser broke out from the buried ruins
of Gibbon Hill Geyser.  Norris Pool, with its gaping, sinter-lined crater,
is probably a spring that was buried long before recorded history that
finally dug itself out.  Bottom line, unless the water and energy have
completely shifted elsewhere, an inactive feature is still there, even if
its surface manifestations have been wiped out.

Another reason to include inactive features is so that, in 20 or more years,
we can match descriptions of an extinct feature to a location.  That might
not seem important for a relatively stable area like the Upper Basin, but at
Norris, where features come and go from year to year and decade to decade,
it'd be nice to have a way to match descriptions to locations, even for
features that are long gone.

Comments on this map:

Errors:
"West Round Spring" is probably Turtle Geyser (The Round Spring Group is not
on this map--it's to the south)
The southernmost "Null" is East Sentinel Geyser

Omissions (these features have dots but aren't labeled):
The northernmost dot in the Chain Lakes is "Clasp" Geyser
The dot just south of Culvert Geyser is "Persistent" Geyser
Variable Spring is one of the dots southeast of Grotto
the Giant Indicator Pool is the dot next to the trail just north of the spur
to Giant
Bijou Geyser is the dot overlapping Catfish
Mastiff is one (or two?) of the dots east of a line from Giant to Catfish
Pyramid Geyser is the lonely dot just northwest of Splendid Geyser (and
apparently not in a thermal area?)
Cyclops Spring is the isolated dot due west of Fan Geyser
Finally, the dot west of where the two trails around Daisy meet *might *be
Punch Bowl Spring

Omissions (no dot):
West Sentinel Geyser is across the river from East Sentinel, but doesn't
seem to have been surveyed
most of Biscuit Basin, and the Purple Pool area (northwest and southeast of
the areas included on the map, respectively)
