Strange. I followed your link, reset all my filters and: nothing happened. I did not see a cache. Even after zooming out and in, moving around the map.
Then I went to my home coords and caches were back. I went back to Yosemite and then the caches showed up, too. I followed the link a second time - no caches. used the little magnifying glass to jump to another location, caches are there, jumped back to Yosemite Valley, caches are there. Something seems to be off.
