While I have county distribution data for the spiders of Minnesota, I currently do not have the infrastructure to produce a user-friendly map-like interface that will enable the public to readily determine where in the state each species can be found. Below is a table showing the number of spider species currently recorded for each county (last updated 13 June 2018).
You can also help with completing known distributions by submitting photographs to the Spiders of Minnesota Project on iNaturalist.
