stream passage is wet, tight, and nasty. A better
way of reaching the Lake Room is by going up
the middle stream passage for about 100 feet
then climbing up 10 feet to a dry upper level
that intersects the main stream. The 20-foottall
by 10-foot-wide passage to the right is the
obvious and correct way to the Lake Room. At
the top of a mud slope is a 7-foot climb-up. The
next 100 feet is a breakdown-floored passage
that averages 15 feet tall by 25 feet wide. At the
end of the breakdown section is a short handsand-knee
crawl that leads to a down-cutting
canyon. The Lake Room is at the bottom of
this canyon. It is a 30-foot-tall room formed
by the intersection of two canyons. Straight
ahead is the stream canyon. Down stream is the
wet, tight, and nasty crawl to the Triple Stream
Junction. Up stream goes for 50 feet before
flowstone blocks the passage. The right canyon
off the Lake Room is a large, muddy flowstone
dam that formed the lake. This lake is 10 feet
wide and looks very deep. By chimneying
over the lake at ceiling level, a sandy floored
crawlway can be reached. This crawl goes for a
little over 100 feet before ending in breakdown.
At ceiling level of the Lake Room is the M
Survey Passage. It can be reached by going part
way up the flowstone dam, then traversing the
wall to a webbing ladder. At the top of the
380
webbing ladder is the
M Survey. It starts
out as a walking-sized
passage. The M Survey
Passage continues
for over 2,100 feet.
It varies in size from
walking to crawling
with the majority
being a hands-andknees
crawl. The M
Survey finally ends at
a flowstone mass. At
the floor level of the
Lake Room, below
the webbing ladder, is
a tight passage named

the Grim Crawl
of Death. It was
discovered by the Harrison Crawford Grotto.
This passage goes almost underneath the lake
