So Many Questions...

I can't get her out of my mind, so this afternoon I returned to her side. I just wrote about her yesterday, but I didn't share my many questions.

I'm hoping you can help me. Here are my main questions, accompanied by photos I just took. Please help me solve her riddle.

What was this before it collapsed?

What uprooted this massive tree?

What's the deal with this tarp?

What lies beneath?
