It was from the 70's or 80's. There's a group of people climbing a mountain, and something bad happens. Someone ends up falling down the side of a vertical face and getting stuck in what looks like a shirt pocket in the side of the mountain. They keep trying to rescue the person, but eventually he/she just freezes to death and is choppered out like a dangling popsicle.

It's been driving me crazy trying to think of this movie's title!

I have a porch, about 150 sq. ft., that is raised about 24" off grade. There was an old, cracked, concrete slab (about 3" thick) set on an underlayment of sandy clay soil, contained by a concrete block wall. The soil over the years settled about 4", leaving a 4" gap under the concrete slab (poured without rebar or any reinforcement). Needless to say, the concrete slab broke right in half and sunk in the middle. I've removed the slab and the retaining wall (which is on a poured foundation below the frost line). I'm putting in a new block retaining wall, but rather than a new slab I want to finish the porch with slate tile. The question is, what would be the best thing to fill the porch cavity with to make sure the tile is stable over the years? Should I fill it with pea gravel and sand, compact the heck out of it and add some drainage, and then tile on the sand? Or should I fill it with gravel and pour a new concrete slab then set the tile on that using mortar and grout?
