It is cedar under the veneer. I went down to take pictures of it, and a friend wound up helping me scrape up all the veneer.
Here's my pictures so far:
A day after the flooding - it got wet inside, but did float, so the top never got wet.
With some veneer peeled off:
A little bit of warping on the lower corners:
All the veneer removed:
I know it needs a good sanding and I don't plan on getting new veneer for it.
So, now I'm down to needing to remove whatever finish/stain that's on the bottom portion and the edges of the lid.
What is a good product for removing the finish off the bottom portion? I'd like to strip the stain out if possible.
