This chronologically sequenced list of highpoints (true summits and liners)
is all-inclusive,
representing both significant and minor efforts.
The following notation is used.
- LINER - The entry corresponds to a liner,
i.e. the highpoint of a political boundary lies on the slope of a mountain.
- NASCENT - The entry corresponds to a "nonascent",
i.e. the summit or liner was attained with negligible elevation gain on-foot.
- NDB - "Not in DataBase" at Greg Slayden's website
peakbagger.com.
Apart from these absences, one may
examine the peaklist
arranged by elevation, prominence, geographic location, and by date of the first ascent.
These descriptors are not mutually exclusive, e.g. one may have a summit
absent from the peakbagger.com database because it has negligible prominence;
and be a nonascent involving minimal elevation gain on-foot.
The following counts apply as of December 31, 2014.
- Total number of entries - 1328
- Number of LINER entries - 43
- Number of NASCENT entries - 180
- Number of LINER
+ NASCENT entries - 18
These are usually "drive-ups" on the High Plains.
- Number of LINER entries that are
NOT also NASCENT entries = 43 - 18 = 25
Thus liners were reached with significant effort 25 times.
- Number of NASCENT entries that are
NOT also liners = 180 - 18 = 162
- Number of NDB entries - 246
There are multiple ascents of 44 peaks, with 37 peaks climbed twice;
four peaks climbed three times apiece; one peak climbed four times (Animas Peak, New Mexico),
one peak climbed eleven times (Cowles Mountain, San Diego);
and one peak climbed thirteen times (Cuyamaca Peak in San Diego County) -
a total of 70 efforts beyond the first ascent.
However Pikes Peak's cog railway was taken the second time;
Santa Ynez Peak (California) involved negligible elevation gain on-foot both times;
Haleakala involved negligible elevation gain on-foot once of two times,
similarly for Chelan Butte; unnamed 3,671 near Chelan Butte both times,
and Highland Peak (Nevada) the second time. Both ascents of "Toilet Top" in Sequoia NP
(a boulder) entailed only about 10 feet of gained elevation.
Thus there are 70 - (7) = 63 non-negligible elevation gain
repeat ascents.
Using the above descriptors, various statistics are available as follows.
- The number of distinct summits attained, regardless of prominence or the mode of
transportation,
equals the
total number of entries - number of LINER entries
= 1285.
- The number of distinct "efforts" involving non-negligible elevation gain
or loss on-foot,
equals the
total number of entries - number of NASCENT entries
regardless of whether liners
+ account of multiple ascents to the same point
= 1328 - 180 + 63 = 1211.
Here, an "effort" generally equates to an "ascent";
the only distinction being to allow
for the case of descending
from a summit to reach a liner.
- The number of distinct "summit climbs" involving non-negligible elevation gain on-foot,
equals the total number of entries - number of LINER entries
- number of NASCENT entries that are not also LINER entries
+ account of multiple ascents to the same summit
= 1328 - 43 - 162 + 63 = 1186.
- The number of distinct highpoints (summits + liners), regardless of prominence,
included in Adam's list at peakbagger.com equals the total number of entries
- number of NDB entries
= 1082.
- The number of distinct instances wherein a summit was reached, regardless of prominence,
and by whatever mode of transportation, equals the total number of entries
- number of LINER entries + account of multiple ascents
= 1328 - 43 + 70 = 1355.
- The number of distinct instances wherein the desired highpoint was reached,
be it a liner or summit, regardless of prominence, and by whatever mode of transportation,
equals the total number of entries + account of multiple ascents
= 1328 + 70 = 1398.
Of these statistics, the number of distinct summits (1285),
and the number of distinct summit climbs
involving non-negligible physical effort (1186)
are likely the most meaningful to the majority of climbers.
The entire peaklist follows, with breaks between calendar years.
