If you're finding yourself Stateside this winter - or indeed if you're already Stateside (damn you)- then you may want to consider a detour through Teton National Park which sits proudly in the top lefthand corner or Wyoming. The scenery in the park is absolutely awesome and worth a trip anyway (can we recommend coming in over Togwotee Pass please?)
But since last year the park has also played host to the Aerial Boundaries ice wall which is getting ready to open for 2010/2011. Last season it was dogged with insurance controversy over who could and who couldn't use it but it seems like this has been cleared up a tad. You can see a gallery of images of the wall here to get you in the mood. Essentially it's 40ft manmade wall of ice - perfect for learning and practising on, and the backdrop is pretty special too. And when you're done there, hop over for a little ski at Jackson Hole. Your options from the UK are to fly straight to JH via Dallas with American Airlines or head to Denver on BA (do you dare?) hit up Breckenridge and drive on from there.
