Summit Elevation

The summit elevation on the first edition of the Imus Geographics Chugach State Park Map is inaccurate. The accurate summit elevation is 5050 feet plus or minus 50 feet. I talked with Dave Imus about this, and in subsequent editions he agreed to omit the elevation because there was no basis for the 5056-foot elevation he initially stated on the first edition map.

Re: Summit Elevation

I hesitated to act on your correction because your suggestion here that the 5056 elevation was not merely unconfirmed, but had not basis at all and thus was something Imus pulled from thin air, seemed kind of extraordinary. But I have attempted contact Imus and there has been no answer, so I will take your word for it.

More on Imus' Map

I think Imus got the figure from some hand-written notes where the last zero in 5050 looked to him to be a six. That's why he has omitted specifying an elevation on subsequent editions. But the 5050 was merely an approximation (plus or minus 50 feet) and not an actual spot elevation.

Re: More on Imus' Map

Thanks--that make more sense. Imus generally seems to be a pretty conscientious mapper.

Update 1/31/11: Imus has responded and confirmed that the elevation was a mistake. He thinks it may have resulted from a too-exact conversion of the approximate metric altitude.
