At the base is a 'snow-duck' under a rock wall beyond which a small rift-like chamber descends about 3m. Straight ahead at the same level, the rift quickly becomes an impenetrable slot through which can be seen a 2m wide passage with an ice floor running down from right to left at 5-10°. This is the source of the strong draught. Below the slot is another low hole, this leaks a vague draught and leads to a small boulder-strewn ledge with a definite blackness continuing to the left behind more boulders. Energetic but nervous removal of these gave obvious signs of a continuation, but other commitments and rain prevented a return. Note therefore it has been <strong>Left Going</strong>.</underground_description> <equipment></equipment> <references><a href="/years/1979/log.htm#id1979-99-1">1979 logbook</a>, <a href="/years/2004/logbook.html#t2004-07-21C">2004 logbook</a></references> <survey>Grade 1 3-d sketch by Tony Malcolm, 1979</p><div class="centre"><img alt="3-d sketch - 21k gif" width="590" height="890" src="99sketch.png" /></div></survey> <kataster_status></kataster_status> <underground_centre_line>In dataset</underground_centre_line> <notes></notes> <length></length> <depth></depth> <extent></extent> <survex_file></survex_file> <description_file></description_file> <url>1623/99/99.html</url> </cave> </body> </html>
