The north entrance leads to 'Slackwell's Stumble', a boulder choked passage with bouldery floor.
The other entrance leads to a snowy slide down into ' John's Winter Wonderland' or alternatively a precarious 3m climb leading to a boring chamber or a bouldery passage into 'Quick wee chamber', with a ledge on the opposite side.
Quick wee has a high entrance inaccessible to us. John's winter wonderland has a too tight passage that echoes and feels as if it may 'go' under the snow.
2007-04 has been tagged by us as such.
We had several 'brown alert' moments on climbs, due to slipperiness and looseness. Another memorable time was when I put in a crap spit, then reached to hang a sling from a natural. The snow under me collapsed, dropping me 4m. Luckily onto more snow. I slid down the snow towards the Winter Wonderland, before the rope became taut and caught me. Worrying.
