Into a chamber

[seascene]

Bit of a necessary absence...now retired, dusted off my Anfibio and am back aboard my sailing vessel seeking silver, gold coins from Sea Otter trade late 1700's to early 1800's. North Pacific Coast pretty much to myself as my ship is full liveaboard with woodstove....no commuting. A bit early to be heading for the north coast but I did some work just recently near the south end of Vancouver Island, an active historic trading area. Good success on 20th century coins. As a point of interest on my last outing got a good dig-able signal on all metal mode 91 gain so I was deep. Digging it out the hole (about 4" diameter) suddenly caved in to a small chamber. Not wanting to dig a huge hole I decided to cover it back up and return with some kind of strategy to explore what might be inside if anything. It has since snowed heavily so I am at least a week to get back in there. I have heard of plumbing snake lights with video feed back for getting into small places .... any suggestions are welcome. Thanks

I live in Northern BC on a Lake that has numerous "First Nation Caches" around the Lake...some on my own property.
Caches were holes and caves dug into the ground in order that these people could leave their fishing equipment in and not have to carry them out each time they visited.

Maybe this is what you have located?
