Here's a tool I have been using

Image high contrast png image of trails. Nothing else in image other than pathways. I have been using it to try to find shapes in the trails. Data is from this GIS dataset: Trails and Pathways

You will have to cross-reference the image to a map since there aren't any trail names. it's nice to have something that you can easily highlight in Gimp or whatever.

I have other datasets that I have previously posted. Putting them here as well.

Trail names All trail names within boundaries, make sure to check the other pages in the spreadsheet instead of just the first raw data page

Historical markers All historical markers within *first* boundary. There are some markers west of I-15 in this dataset.

If there are any other data sets that you would find useful, please feel free to drop a comment or DM me.

Edit 1: All Trails list A link that filters trails outside of the area (some trails west of I-15 remain). You can apply additional filters to this list, but moving the map will cause the boundary filter to refresh.
