What distance should be planned from the trailhead to the pass?

gap · gap-taboose-mileage

The approximate USFS guide gives 6.5 miles; the matching official trail dataset terminates at milepost 7.6146 and has different GIS length attributes. Different survey/measurement methods or editions may explain this, but the discrepancy is unresolved. Traversal is connected with unknown canonical distance; no arithmetic or map scaling resolves it.

Open question. The following evidence does not resolve this gap. Use the recorded question and reason to understand what needs confirmation.
