In reply to Nicholas Livesey: California, summer 2008. We were lucky enough to get permits for Mount Whitney, highest point in the lower 48. We drove to the end of the road, packed bags full of camping gear, climbing gear and food. Walked in for about 5-6 hours, elevation gain of 1500m, some pretty exciting scrambling and some really dull scree.
We pitched camp at around 4000m and looked forward to the East Buttress, a classic 12-pitch VS, the next day. But we woke up to cloud. "It'll burn off during the day" said the passing mountain guide. So we set off, scrambled up to the base of the route and started climbing the perfect granite. Three pitches up, it started to snow. It soon became apparent that it wasn't going to stop and clear, and the holds and cracks were rapidly filling up. So we abseiled off. Luckily, this was relatively easy and we returned to our tent. What was even luckier was that the slightly damp matches lit the stove.
The next morning we woke up to the beautiful blue skies we had enjoyed for the rest of the trip. But the route was still covered in snow. So we lit the stove with the last match, ate our porridge, and spent another 6 hours walking back to the car.
Maybe next year we'll give it another try.
