Do PLBs give elevation as well as L/L?

The article above said 'He had “cliffed out” on the side of Elephant Tusk...', so I am assuming that he was quite a bit above the base level. If they don't, the rangers could have been within 50' of him horizontally, but he was too high to be seen. He may have only waved the blanket when he heard/saw the chopper, but if he didn't know the rangers were below him...
