i have a huge sink hole under my garden .It sank alittle last year; this year a hole opened up. when I started digging; we could tell its where they buried trees from clearing the lot 11-14 yrs ago. i hope thats all thats in there(could be 5 gal paint buckets and caulk tubes etc..) We found pine bark down in the hole and smelled rotting wood. What should i do. Someone said fill it w/ cruch and run but its under my garden. That is not the way i want to go.
