Survey YO
Crew : Terry Mcclanathan, Kevin Flanagan
Objective : tackle a potential borehole sized lead left during the YY
survey.
New Survey : ~265'
I arrived friday to await Terry and enter the cave to camp. We decided
due to the lateness of the hour to instead head in first thing saturday
morning and knock off some day leads in either the YY or FLAD area's.
After a slow start we where on our way in at about 10am, first
encountering the much needed rebaly, we lost a little time on it, and
then the redirect. I placed a soft interface on it, and Lew improved it
on his way out. I consider the redirect much improved and more caver
friendly. Thanks lew.

So in we headed, this was first mdc trip for terry and he was very
impressed by mdc. We ran into lew who had just finished his bolt climb
for the weekend shortly before our arrival and then off to find YY. For
those looking for a quick reference it is the pit below the rock with
lews(?) slings on near the end of the Y survey.
At the end of YY looked like a borehole passage, but for lack of a rope
we did not know. We set out to bolt a line down it. After a few swing
with the self drive halfway into the rock we decided to find a harder
wall to bolt into. Most of the limestone is 'rotten'. The drop is a
good 15' drop into a 30' wide pit with a north heading canyon drain. So
we decided to follow the muddy mess for 265'. The first 2/3 is very
muddy and has running water. The canyon headed almost due north making
the easy for/back sight calculations. Everything was coated with mud,
with a limited number of formations sticking out at odd locations.
Near the end of the survey we lost the water but encountered a dry
stream bed about 2 feet wide in a 4 foot wide canyon passage that goes
... at least arround the corner we looked arround. So being completely
exhausted we decided to turn arround just when the passage turned from
miserable to decent.

Egress was slow, arriving out of the cave just as the sun was coming
out. There was some debated throughout the trip as to the time since we
both lacked watches.
We never ran into the Bob's survey group so I never got my books
signed.

Note : we left the YY drop and YO drop rigged.
