- Shipwreck is the next abandoned gravel pit west of the CO river SWA ponds (which
are west of Corn Lake on 32 rd) off of D Road in GJ. As you head west on D rd
from 32 it is an unmarked left off of D Rd just after Bristol which would be a
right. It has been described to me as 30 and a quarter, which does not exist on
maps. It is a roughly paved road leading to a dead end at a house. Those people
are not excited about having their road blocked so pull over. The pond is to the
west and used to have a canoe "wrecked" on the main island but that is gone now.
