While an elevation graph like this can be handy, it is easy to find the information on the maps themselves. Just turn on terrain mode, and zoom in to the desired level of detail
For example the area around the tunnel, at a zoom that shows elevation contours, ski runs, and US6 zig zags over the ridge while I70 goes straight through the tunnel. And for greatest detail go to streetview.

You can even get streetview images of the ski runs.
All true, but working the map for long distances this way would take a long time. I have done this when I want to know what the elevation of a specific location, but when traveling letting the plot run first is the easiest/fastest. My guess is not everyone knows of either way to do it (terrain mode/plotting elevation) or think of it ahead of time.
