It is an old rock quarry. In that quarry, there is a wall that starts out at approx. 20ft and heads west across the quarry to 90-ish feet. On the north side of the wall, it is very cold < 40 deg F., it can get very deep (100ft to 142ft.), and there's not much to see on the north side of the wall. There is only one dock entrance to the deep side. The "shallow side" has all the sights. There's a bus (35ft), motorcycle(25ft), VW bus (20ft), Dr. Pepper machine (30ft), a totem pole(20ft.), a grumman airplane(15 (tip of tail wing) to 35ft (landing gear)), there is a "tower wreck" (50ft), 4 large tubes (50 feet top, 65 feet bottom), and a bunch of trucks and little boats at numerous depths. there are 4 shallow side entry points that are seperated from the deep dock, (3 docks and the 1 ramp). They do have a web-page

I promise you guys that the water will be cold when you head up there. I'm not getting in...I don't think, but do hope to make it up on either Sat or Sun and maybe make you guys lunch or have something warm to drink / eat.
As for lodging, there are a bunch of hotels in Findlay which is approx. 20 minutes from the dive site. Gilboa also has a bunkhouse, but I have no idea what it costs, or what the quality of it is. Ber would know more about the hotels, normally when I'm staying, I camp, but it is a little cold to be throwing out the old coleman tent that time of year.
