Field notes
State listings include links to individual springs, with examples showing temperature and access categories alongside location details. The homepage counts 30 primitive springs and 14 recorded as free to visit, but cautions that source temperatures may not match the water at a soakable pool. Its data notes say access and fees are included only when a source states them, so missing information is not evidence of free access.
