Same here. I wouldn't go traipsing through the woods looking for a spring at a set of coordinates without first finding out who the landowner is and contacting them for permission. (If it's not public land.)
In one case I found, the USGS point for the spring is on public land, but the actual spring is on a private inholding. This, of course, led to an error that caused the site to list it as "public."
Are they still shown when you select the 'Open to public filter'?
