Welcome to the County Highpointers information map page.
The following list both describes and provides hyperlinks to maps of an informational nature
of interest to the county highpointing community. Certain links lead to lists rather than a map,
and, in most cases, a corresponding map exists anyways.
Information Map Links
Large County Map
Produced by the United States Census Bureau, this map portrays
all counties and their statistical equivalents (2.1 megabytes).
"Pinpoint" Maps
Sponsored by Dave Covill, these maps display county highpoints
by red dots. Nearly complete, the maps lack only information from
parts of Louisiana and Mississippi. A main, USA-wide map is accompanied
by a 3 x 3 grid on nine regional maps for higher resolution.
These maps facilitate rapid location of highpoints for planning purposes,
e.g. which counties may be efficiently combined in the same day; back-to-back days;
or on the same trip.
The maps are clickable to facilitate navigation in-between them.
Access Category Mapaccess category definitions
A work in progress by Edward Earl that shows access restrictions by color code. E-mail him with highpoint access information
after removing the ".county"
portion of the address (present to foil web crawlers).
Ownership Category Map
A work in progress by Ken Oeser that shows county highpoint ownership by color code.
First Ascent Map
A work in progress by Ken Oeser that identifies first ascent highpointers by color code.
Elevation Map
(color-coded in thousand foot intervals as described by a legend)
- by Aaron Maizlish
Highest 50-100-150+ Elevation Mapthe corresponding lists
A work by Dave Covill showing the highest 166 county highpoints in all fifty states
(everything above 10,000 feet); and the highest 157 eastern highpoints (all above 3,000 feet)
in color-coded groups of 50 counties.
High Five Map
(The five highest county highpoints in each state.)
- by Jerry Brekhus
Low Five Map
(The five lowest county highpoints in each state.)
- by Michael Schwartz
Elevation Gain Mapelevation gain discussion and listselevation gain rules
A work in progress by Edward Earl using a definition of elevation gain
determined as an "average" result after polling active county highpointers
for their individual elevation gain definition preferences.
E-mail him with elevation gain information
after removing the ".county"
portion of the address (present to foil web crawlers).
County Highpoint Prominence Map
A work in progress with contributions from Bob Bolton, Jerry Brekhus, Edward Earl,
Andy Martin, and Adam Helman.
Class Ratings Mapclass ratings definitions
A work in progress by Edward Earl for the least technical route to each highpoint. E-mail him with class ratings information
after removing the ".county"
portion of the address (present to foil web crawlers).
County Highpoint "Triple Crown" Map
Triple Crown county highpoints are simultaneously APEX,
5,000+ feet of gain, and ultra (5,000+ foot) prominences. There are only ten
such triple crown summits in the lower forty-eight states.
County highpoints with at least one of these descriptors are also shown
with colors corresponding to the specific descriptor combination, e.g. cyan
represents the combination of 5,000+ feet of gain and ultra prominence.
High Five Average Elevation MapAverage County Elevation Lists
Carl Mills has determined the average elevations of counties throughout the United States.
The map portrays the counties with the highest five average elevations in each state.
The lists include dozens of additional counties.
Highest Five Standard Deviation in County Elevation MapStandard Deviation in County Elevation Lists
Carl Mills has determined the counties with the largest standard deviations in elevation.
The map portrays the counties with the highest five standard deviations in elevation for each state.
The lists enumerate the highest standard deviation county for each state;
and the highest standard deviation counties regardless of state.
"Helman Counties" MapHelman Counties List
A map by Jerry Brekhus showing the county in each state with the
greatest elevation difference between its highpoint and lowpoint.
Lowest Fractional Relief Map
A map by Carl Mills showing the fifty counties with the
smallest values of the fraction (highpoint elevation - lowpoint elevation) / lowpoint elevation.
Topographic Map Links
A work in progress by Glen Bock that provides links
to topographic maps for county highpoints.
Latitudes and longitudes of highpoints are found within
the addresses of the hyperlinks to the topographic maps.
Azimuthal Equidistant Projections portray great circle routes as straight lines....
New York City
Scale is 50 km / centimeter. Distance circles are shown every
100 km to 500 km. Compass bearings are superimposed.
World centered on Del Mar in
San Diego County, California.
Scale is 2,000 km / centimeter. Distance circles are shown every
4,000 km to 20,000 km - the distance to the antipodal point off Madagascar
in the Indian Ocean. Compass bearings are superimposed.
