Check out this trip next to a river down in a valley between some mountains.  The last landing was on a strip that was the shape of a boomerang, having a significant bend in the middle with each leg extending about 150 feet. 

Short base was about 45 knots, slowing to 38 knots on short final.   Watch this along with a few other approaches and touch downs into less than desirable areas.  And check out the full description on the Katmai blog.  (Link on left nav bar.)

Please remember that while this type of flying is fun and the rewards are great, it takes a lot of skill, proficiency, a good assessment of your and your airplane’s capabilities, the right aircraft, and mental discipline.  It is dangerous, and only experienced back-country pilots should attempt it.
