Yellowstone to Yosemite

Just spotted the Cooncil's "what's on" guide with this:

Irvine Butterfield’s illustrated lecture will describe the glories of America’s national parks.

Experience the glories of America’s national parks through the eyes of Irvine Butterfield, renowned author and photographer. Starting beside Yellowstone’s geysers, Irvine’s photographic journey will encompass the sculpted rocks of Utah, Grand Canyon, Bryce and Zion, finally culminating amongst the hanging walls of Yosemite.

The lecture, which is being organised by the North East Mountain Trust and the Cairngorms Campaign will also see the launch of Harvey’s new map of the Cairngorms.

Details - hopefully clear enough prep and marking to allow me to get to that. I assume the map launch is this one ...  ooops, I've had mine for a few days after it became available. Nice overview map.

Speaking of maps - I was in Blacks the other day with the OS 3-for-2 deal and realised that I wasn't sure which maps I already had. I'll need to start a list on the pda.
