Yesterday I tried to go to the yard by clicking the url in the url bar, and saw that you can search the yard regularly while the exploring is available.

So, this url works:

http://www.prisonblock.com/yard-search

When the new yard can be accessed through:

http://www.prisonblock.com/explore#

Of course it's no longer up, so you probably can't get to it to check, but is this supposed to be possible?

Yup,right,i was refreshing that search page and wasted 10 odd minutes..then came out,clicked bushes again ,then was in the dungeon.
