1) driscoll north entrance
2) driscoll west entrance
3) a bit down the hill from #2
4) from the bottom of the hill
as you can see, the west side has some serious elevation changes in it. also note how above each entrance there's a "divot" in the top layer of stonework layer. this divot lines up with (and is the same width as) each entrance area. if the texture of the stonework could be closer to what's used for the hopkins observatory that would be great.
