I got the picture off the net. I just did a search on Google for the Spiegle Grove and then clicked on images. There are a few more I came across of holes like those in the picture but this was the bast one I saw.

mempilot:This is kind of hard to pinpoint anything, but may help visualize.
HarleyDiver:Two questions, is the opening square like the one in Scott's picture or Oval like a hatch? The entrance to the wheel house is a hatch.
Do you remember the depth? The Wheel hose starts at about 75-80' & drops down to 105ish. Those cutouts in the picture are probably about 60-65' .
Padipro:ROFLMAO...Damn Eric you think they're small enough?
