Finding food was less difficult than might have been expected. While the beach, itself, was devoid of anything beyond wreckage and other junk that had washed ashore, among this junk a pair of crates with various foodstuffs were found. They were relatively dry, compared to how badly it could have been, and from the general looks of what was within, edible. Though it looked to be mostly dried meats, food was food.
As for shelter, the beach doesn't seem to be anything but out in the open. It looks like it might be possible to build a crude tent, of sorts, from pieces of the wreckage, but you can't see much else worth using on the beach. Checking towards the treeline farther inland reveals that the treecover seems to get very thick, very quickly. Whether anything is alive through there, you can't tell, but it looks to be too packed with underbrush and growth to provide any room for shelter without a lot of work.
