<h2><a name="survey">The</a> Survey</h2>
|
|
|
|
<p>Surveying was not the strong point of this year's expedition; it is hoped
|
|
that we can do better next year. The entrance series of 115 to the head of
|
|
the Ramp and 41 down to the pitch just above Junction Chamber were surveyed
|
|
to BCRA grade 5 in 1980 and these surveys have been published in Proc. UBSS
|
|
Vol. 16(1). 115 from the ramp to the bottom of the pitches and the connection
|
|
were both surveyed to Grade 4 (the survey of the connection is reproduced
|
|
here), making a closed traverse with the surface survey between the
|
|
entrances. Unfortunately, though they closed vertically to within 2m, the
|
|
plan closure was wildly out. It is thought that this might have been due to a
|
|
sticky compass on the 1980 survey. The length of Pete's Purgatory was found
|
|
to be 800m, but no other details were measured. Below this, the section of
|
|
the streamway from the inlet to the 'twelve foot climb' (marked as c5) was
|
|
surveyed to grade 3 and this is extrapolated downstream on the grade 1 survey
|
|
to give a total depth of 680m plus or minus 40m. One point which the
|
|
elevation does not bring out is the way that Stellerweg spirals round on
|
|
itself with changes of direction at the big pitch and at Junction Chamber.
|
|
The final direction of the streamway seems to be northwest - heading back
|
|
into the mountain and away from the lake.
