Answer
Hi, Chris:

Thank you for sharing these very interesting images.

Your creatures are larvae and at least one pupa (the first image) of the "Pigeon Horntail" wasp, Tremex columba .  Here is a blog post I wrote about them:

plus, a video of a female laying her eggs:

With your permission, I would like to incorporate your images into one or both of these blog posts, with copyright retained by you, and giving you full credit.  Just reply in your evaluation if this is agreeable.

Thank you for sharing your discovery!

Sincerely,

Eric
