* From the 1964 D&RGWRR Condensed Profile.
† The 1964 Condensed Profile also shows 369′, unlike the 1988 D&RGW chart. This tunnel is bare rock throughout, so somebody wrote it down wrong, transposed digits, or mis-measured it. Google Earth agrees with the 369′ measurement.

The 1964 Profile does not seem to show all the revised tunnel lengths after portal revisions.
