FOOTNOTES:

NEW ELEVATION: All of the elevations that we grew up with, those that still appear on the USGS 7.5' maps, are outmoded. Substantial advances in geodesy (the scientific measurement of the earth's shape) have rendered obsolete the vertical datum on which they were based. "New Elevations" in this table improve on existing elevations in two ways: 1. The NAVD88 elevations have been applied. NAVD88 is the newer vertical datum for North America that is compatible with commercial GPS units. 2. I have added footage to mountains in the frequent instance where the benchmark (published) elevation is known to fall short of the true summit. More detailed notes on both of these adjustments will appear in a future article in the theory section of this website. Virtually all new elevations will range between -5' and +15'.

OLD ELEVATION: The "New Elevations" may be interesting in their own right, but they aren't useful for prominence calculations. This is simply because all of our saddle data is based on topographic maps that used the older, NGVD29, vertical datum. Since prominence is a measurement of the difference between two values, it will be more accurate to compare apples and apples.

MOUNTAINS:

Six digit codes in the footnotes section refer to the benchmark PIDs that reference the summit on the National Geodetic Survey website.

[1] Rainier: Summit reference is a definitive GPS survey published in Point of Beginning, 2000. The key saddle is in the town of Armstrong, BC. The 1:50,000 DEM for BC gives the saddle a low value of 359m (1,178'). According to Robin Tivy, the 1:50,000 Canadian map puts the KS between 360m and 380m. Therefore a new saddle value of 370m (1,214') has been assumed pending further investigation.

[2] Whitney: The USGS 7.5' provisional map gives a value of 14,491'. This was in error, likely based on the reading of a benchmark that was not on the true summit. The old elevation value for Mt. Whitney was 14,494' and then 14,495'. The NAVD88 value for the highest benchmark, TQ0506, is 14,505'.

[6] San Jacinto: The 7.5' quad elevation of 10,804' is erroneous. The correct NGVD29 elevation should have been 10,831'. In addition the benchmark rests 8' below the natural summit for a total elevation of 10,839'. The newer NAVD88 elevation is 10,834'+8'=10,842'.

[24] Washington: The Key Saddle is on the Champlain Canal near Hudson Falls, New York, 43º18'59"N, 73º31'46"W. Note that the prominence and saddle elevation were corrected 3/13/2005.

[27] Borah: See also the Americas Roof report on Borah that explores the rumor that Borah gained 7' elevation in a 1983 7.0 earthquake. The NGS benchmark PID is PZ0770 "Beauty Reset".
