One thing Geocaching.com doesn’t make easy is finding the location of archived caches. I grabbed my whole history of pocket query files (back to April 2004) and built a GPX file containing all archive caches I could get my hands on. The map below shows up to 50 miles from Peoria, but my data is most complete within 30 miles of Peoria.
Take a look if you’re interested. There have been quite a few times when I’ve wanted to know “what was that cache that used to be here?”, and this map has helped provide answers.
