<p><b>Altitude:</b> 1697m
<p><b>Location:</b> "about 6m above
<a href="../handbook/survey/lasers.htm">Laser rangefound point 0/5</a>"
(which is above gully containing <a href="../plateau/107.htm">Kat. 107</a>
and marked with an alloy tag stamped "LASER 0-5"). The cave was looked for
but not seen in a visit to this laser point in 1998. A second cave 100m from
0/5, uphill to the left, was not given a number because of evidence of
previous exploration, but should be investigated further. 157 was relocated
in 2001, visible to the right of the route up to 204. It was marked with faded
yellow paint.
<p>Entrance shaft of 50m until gap between snow and rock became too perilous
in 1987 - bottom still out of sight. About 25m below the karren, a rift
passage leads off from side of shaft into parallel shaft with aven. This
shaft is of unknown depth but has recent looking bolts of unknown origin. It
is just conceivable that these bolts are in 107, but far more likely that
the cave had been looked at by GSCB who were in the area on a reconnaissance
in 1986 (?) and more seriously in 1987.
<p>The second cave has a walk-in entrance, splitting just inside. The left
passage comes out below a shaft from the surface, and apparently continues
unexplored. The main passage reaches a 10m pitch, also below a surface
shaft, which drops into a chamber. To the left is a short passage to an
undescended pitch of about 10m, while to the right are three ways on. First
is a rift, then a passage with an ice floor, and finally, half back towards
the entrance, is a passage emerging below another surface shaft (passed on
the surface just before reaching the entrance). This final passage also
appeared to continue. Because a large carbide pig was found outside the
entrance, it was assumed that someone else was in the course of exploring
this cave.
<p><b>Exploration:</b> Uncertain. Rediscovered CUCC 1987
