While searching cashe info I stumbled upon this cool interactive map.
I hope the link works. Cut and paste is an option.
It's PRE-Clovis but still great for ice age references,
I find most of the sites lacking in proof of pre Clovis people
but that's just me.

If you find the site scroll down to the box on the left
Explore Pre Clovis Sites and click it.
Good luck with the links.
Cut and paste usually always works.
