Seems to me this may be a matter of personal preference, Duane. When races I am associated with use inexperienced personnel for course layout, mistakes are made often as not. I often hear that it is difficult to read maps in dim light. Yes, flashlights help. I do use reading glasses. I have no problem reading it. However, reading it and using it to full advantage on race day seem to me to be two different considerations. I am not just talking about myself here.
I understand the convenience of having everything on one page. Obviously, Bell Bellevue did as good a job with this particular map as anyone could, I can guess. The term I once heard to describe a single page with this much data on it is "too busy".
I recently measured a 5K XC course for certification that traversed several open field areas where defining the path required a lot of interim measurements and map insets. There were way too many insets to include on a single page, even separate from the map. Including all this data on one page would have required a magnifying glass the size of a bathroom mirror to render this data legible to anyone.
I suspect the issue of too much for a single page has been thoroughly discussed in the past. I am not familiar with the reasons for confining everything to a single page. What are the reasons for this restriction?
