Design Usability Question (top, bottom, footer)

So im looking to add some "archive type" navigation to the site. Dont really like sidebars and definitely do not like the mobile pop out menus. This site is basically a running timeline, going back years.

Need a way to jump between years and have subs for months (i know it sounds like archives) i just really dont like the look of them. I was thinking like static jump links / buttons / images in the footer on the mobile (possibly the header)

Maybe a floating / move with scroll list (kinda like the floating socials)

Thoughts ? Ideas?
