Joyce Parsell Passes Away

The Highpointers Club is saddened by the death of Joyce Parsell.  Joyce had conquered 37 state highpoints and 40 state low points. 

Joyce’s husband, Jack, wrote the first definitive guide for tripointing, and Joyce was his partner in these adventures, visiting 38 tri-points. 

Joyce passed away peacefully on Oct. 4.  Her daughter, Susan, has asked that any donations in her honor be sent to the Highpointers Club Scholarship Fund.

Joyce and Jack were featured in an interview in one of the club newsletters in 2003.

State Highpoints May Offer Amazing View of 2017 Total Eclipse

With a new observation tower and a cleared top, Sassafras Mountain might be a prime spot to view the 2017 total solar eclipse.

With a cleared top and hopes of a new observation tower, Sassafras Mountain might be a prime spot to view the 2017 total solar eclipse.

[Ed: Club members may want to read the updated article (with times) “Two Minute Highpoint Party or ‘Highpointing In the Dark'” in Issue #117 – Second Quarter 2017 of the newsletter (in your mailboxes now)].

For the first time in nearly a century, a total solar eclipse will be visible across the United States, and given the projected path of totality, highpointers may be able to head to the top of  a few different states to watch the event unfold.

The Washington Post recently posted an article showing the projected path, and gives more detailed listings of where the eclipse can be seen in totality.

A 51st Highpoint? Puerto Ricans Vote in Statehood Referendum

Cerro de Punta, the highpoint of Puerto Rico (Credit: Ratzer1 | Wikipedia)


Highpointers may have to find a way to reach a 51st highpoint as Puerto Ricans headed to the polls Sunday to vote on a statehood referendum.

Voters were presented with the option to vote for independence/free association, keeping the status quo, or statehood.  The result of the vote, known as a plebiscite, is non-binding as the United States Congress would have to formally set forth conditions for statehood, and this not required in response to the vote.

However, let’s go down the rabbit hole and assume that the vote comes back supporting statehood (a strong possibility as many who oppose statehood are boycotting the vote), and Congress votes to extend statehood to Puerto Rico.

If Puerto Rico were to become a state, it’s highpoint is Cerro de Punta, a 4,390 foot mountain in the Cordillera Central, a mountain range that divides the island.  On a clear day, San Juan, which is 75 miles away, can be seen. 

The mountain’s elevation would place it between Kentucky’s Black Mountain and Vermont’s Mount Mansfield in elevation ranking. 

Opportunity to Learn about Geocaching at the 2017 Massachusetts Convention

While chasing down the 50 highpoints, several highpointers dive into other adventures such as tripointing and lowpointing.  At the 2017 Highpointers Massachusetts Convention, highpointers will get the chance to learn about another hobby–geocaching.

For the uninitiated, geocaching is a real-world, outdoor treasure hunting game using GPS-enabled devices.

Some state highpoints, such as Backbone Mountain, Maryland, have geocaches hidden on them.  

Club members will have the opportunity to mingle with the geocachers of Berkshire GeoBash during the Massachusetts 2017 Highpointers Convention “Afternoon Delight” at Freight Yard Pub in North Adams on Friday, July 21st. The fun starts at 1 PM and goes until the last person crawls home at close.

Highpoints by Volume

While looking for various mountain metrics I found the ORS (Spire) Measure as well as Tim Worth’s Steepness Measure which is a simplified version of ORS. I decided to try an intermediate measure – measuring the volume of the peak near the summit (100m) and at its shoulder (800m). The thought being that spires/towers will have a high volume at 100m, but their 800m volume won’t be that much larger. Whereas a flat-topped mountain will have a low volume at 100m, but their 800m volume will be much larger.

Imagine taking a core sample (100m or 800m radius) centered on the summit. Lower/drill a cylinder down until the entire bottom edge is contacting rock. This will occur at the “Max Drop” value Tim Worth calculates. Cut the cylinder off at this depth and calculate the volume of rock in the cylinder (core sample).

The ORS/Spire Measure uses integrals and a complex function to calculate the volume of a peak. I simplified this by measuring discreet rings from the center to the cylinder’s radius. I used 20m increments for the 100m cylinder and 100m increments for the 800m cylinder. The first level is simply a right triangular pyramid (triangle in 2D). All subsequent layers are a horizontal triangular prism (wedge) (triangle in 2D) and a vertical triangular wedge (cheese wedge) (rectangle in 2D). For all angles except for the Max Drop (Max Bearing), I add in a final vertical triangular wedge (cheese wedge) (rectangle in 2D) which brings all angles down to Max Drop level. You can see this in the graph below for Borah Peak, Idaho at 100m. The left side is along the Min Drop bearing, while the right side is along the Max Drop bearing.
The image on the right shows an exaggerated view (30° angle instead of a 1° angle) from the top. The color-coded layers match in the two graphics. The shaded triangles would form small right triangular pyramids but these were not included in the volume measurements below.

We can compare the 100m and 800m volumes in a couple of ways:

Let’s look at Mount Greylock, Massachusetts which has a median 100m volume but a higher than median 800m volume:

while White Butte, North Dakota has a higher than median 100m volume but a lower than median 800m volume:

and Granite Peak, Montana which has a very high 100m volume but an mostly equivalent 800m volume to Mount Greylock:

This is where I throw up my hands. While I (Clint Kaul) consider Granite Peak to be “steep” at 800m (and at 100m), I personally wouldn’t call Mount Greylock “steep” at 800m. Although they have roughly equivalent 800m volumes. I have a feeling we need an additional factor to help determine “steepness”. Maybe factor in the peak’s Prominence or the Max Drop value? Or look at the ratio of Avg Drop to Max Drop (as seen in this graphic – AvgMax xxx is the (Avg Drop)/(Max Drop) at 100m and 800m). The idea being if the Avg Drop is close to the Max Drop we are looking at a “conical” peak, while an Avg Drop far from Max Drop might indicate a flatter peak with a steep ravine/cliff on one side.

Looking at the radar plots above, maybe count the number of lobes (number of ravines/cliffs) or the size of the lobes or the variance in the size of the lobes [see the “Max StdDev” columns in the 100m/800m specific tables below]? Or perhaps look at intermediate angles (for example, 0-20, 20-40, 40-60, 60-80 and 80-100) and compare them to the overall angle (at 100m in this example) [see the “Sub Angle” columns in the 100m/800m specific tables below]. Another crazy idea is documented in Appendix – Drops as a Waveform. If you have comments/thoughts on this, please contact me

This heat map is color-coded based upon the Volume metric at 100m.

I’ve recently calculated the maximum sub-angle and standard deviation of the drops in all directions at 100m. This graphic summarizes this information. It seems like the standard deviation is a good indication of the steepness near the summit area.

This scatter plot compares the standard deviation (stddev) at 100m versus at 800m. While the comparison doesn’t mean much, it helps identify comparable peaks.

Let’s look at Massachusetts (left) and Oregon (right) which have equivalent stddev at 800m, but Oregon has a vastly greater 100m stddev. Looking at the 100m ring (blue) you’ll see Massachusetts is much flatter than Oregon.

Now let’s look at South Dakota (left) and Texas (right) which have equivalent stddev at 100m, but Texas has a vastly greater 800m stddev. Looking at the 800m ring (orange) you’ll see Texas has more ridges/valleys than South Dakota.

Appendix – Drops as a Waveform

Looking at the lobes in the radar plots got me thinking. How do I calculate the area? It turns out to be "Avg Drop" * 360. Initially I was going to “unwrap” the circle into a straight line and figure the area under the line. For example, see Massachusetts (left) versus Montana (right) at 100m:

That triggered the crazy idea. What if we treat this as a [triangular] waveform? Maybe by looking at amplitudes or frequencies we can find a “steepness measure”? To test the idea I sub-sampled 256 points out of the 360 data points and applied a fast fourier transform to come up with the following table.

This table shows the “statistics” and “fft” metrics for 100m and 800m
Avg 100 – average drop at 100m in feet
StdDev 100 – sample standard deviation of the drops in all directions at 100m
NyqF 100 – Nyquist frequency at 100m
Freq 100 – maximum frequency at 100m
Avg 800 – average drop in feet at 800m
StdDev 800 – sample standard deviation of the drops in all directions at 800m

Freq 800 – maximum frequency at 800m

Climbing season begins at Denali National Park

KTUU (Talkeetna, AK) is reporting that the climbing season for Denali National Park is starting. According to park spokeswoman Maureen Gualtieri “We’re expecting a pretty typical season in terms of the numbers of visitors numbers of climbers on the two peaks.”

Highpoints by Prominence, Isolation and Dominance

This map is based upon Prominence and Isolation data from Peakbagger and Eberhard Jurgalski’s work on Dominance. The icons are color-coded by their Altitude Class (Dominance). Each summit is linked to its Prominence Key-Col (horse icon) by a purple line and has a separate orange line drawn to its ILP (Isolation Limit Point).

These two scatter plots show the Prominence height versus the Isolation distance in linear (left) and log (right – for better readability) scales. I then ran a clustering algorithm to form clusters of peaks which are color-coded in the table below.

This table presents other meausres used to quantify summits:
Prom – Prominence is the vertical distance between peak and key col
Iso – Isolation is the radius of dominance
Dom – Dominance as defined by Eberhard Jurgalski

* – Note that Connecticut doesn’t have prominence or isolation because it is a contour line on the side of Mt Frissell. Thus these measures have no meaning.

Edward Earl, over at COHP, has produced this map showing each state’s highpoint (HP), most prominent point (PP) and distance isolation point (IP). Please click on the map to see the map’s legend.

Highpoints by various Difficulty measures

This map is based upon the work of Dr. Thomas Martin and his classification of the 50 State summits. The icons are color-coded by their Martin Classification and have three arms representing the Gain and round-trip Distance.

These two scatter plots show the Gain versus the Hiking Distance in linear (left) and log (right – for better readability) scales. I then ran a clustering algorithm to form clusters of peaks which are color-coded in the table below. These clusters are slightly different than those of the Martin Classification.

People are always curious about “How hard is it?”. This table presents the highpoints with various “difficulty” measures:
YDS – Yosemite Decimal System is mostly a technical climbing rating system
COHP – COHP Class Ratings is mostly a technical climbing rating system
Martin – Martin Classification based upon elevation gain and distance hiked
Gain – Total vertical gain in feet on the “standard” (easiest) route
Dist – Round-trip distance (trailhead to summit) in miles on the “standard” (easiest) route
