Distances, Azimuths and Elevation Angles Of Peaks

The table below gives, for each of the listed peaks, the distance, azimuth and elevation angle of the other peaks. Be warned that any given peak might not be observable if it is blocked by an intervening peak or ridge.

See How To Calculate Distances, Azimuths and Elevation Angles Of Peaks for the formulae used, as well as definitions of these parameters.

I obtained the coordinates for these peaks from the USGS Geographic Names Information System. Hence the names in the table are the official names, so be aware that Mt. Baldy is actually called Mount San Antonio by the government, even if no one in Southern California uses that name!

To use this table, look down the first column to find the peak on which you are standing. Each peak has three entries in that column: the official peak name, the county in which the peak is located, and the name of the 7.5' USGS Topographic map on which the peak is located.

The rows corresponding to that entry give the observed distance (in miles), azimuth (in degrees), and elevation angle (in degrees) for the peak named at the top of each column.

The azimuthal angle is the direction in which you need to look in order to see the observed peak. Angles of 0° = north, 90° = east, 180° = south and 270° = west. The elevation angle is the distance above (positive) or below (negative) the horizon at which you'll find the observed peak.

See Highlighted Instructions For The Use Of This Table for further instruction.

The table is not complete, with only 19 of the most prominent peaks of the Hundred Peaks in Southern California listed. The columns are roughly ordered by the order of the SGM peaks from west to east, followed by approximate azimuthal order for the non-SGM peaks as seen from the SGM.

One way to use these parameters is to plot the elevation angle vs. azimuth for a given location. Many spreadsheet programs such as Excel97 can open an html file, making it simple to plot one row vs. another to accomplish this. See View From Mt. Wilson and View From Palomar Mountain for examples.

A much better way to plot peaks as seen from a given location is Find mountain and peak name as seen from any location.
