Does anyone know how many cellphone towers there are in the Mammoth area?

Is there a good map? What I found so far doesn't get down to the detail level neeeded.

Getting warmer.

@ctadlock- Great search effort which everyone appreciates...everything helps but physical searches are the most valuable since they're ultimately how Matt will be found. Note the button you found uses British/Canadian/Aussie spelling, not the American spelling.

@zBrown- Discussed before, the Verizon logs included 3 sites in the Mammoth area...by the library, near Norco (auto service center), and by the top chalet on top of the mountain. The exact lat/lon provided were confirmed on Google satellite and street views and incidental photos of the top chalet. The "antenna finder" site is the wrong context for your investigation and the map only shows 1 of the 3 Verizon sites (it shows tower structures only and not the many different "tenants" on a typical tower). Hope this helps, send me a message if you need the exact lat/lon.

On the same site, the antennas map shows 90 within 4 miles of 96 Beaver Ct., while 5 towers are shown on the tower map. It even breaks down antennas as to single or multiple. It's an interesting site. Trying to see if the 4 mile range can be expanded.


EDIT: URL's have had carriage returns inserted to stop stretching the page.

^^zBrown- That's way better! On the map and list, #1, #12, and #52 are the 3 locations of Verizon sites. FYI, anything in the 450 or 800MHz band is CDMA to/from phone handsets. Other Verizon frequencies are for their internal infrastructure.

A cell site is 9-15 antennas arranged in a triangle; each one covers a 20-40 degree slice. The approximate direction from the cell site can be figured out by knowing which antenna(s) a phone "hit". I seem to recall that Verizon won't research it without law enforcement involvement.

From personal experience, Verizon coverage west of Minaret Summit is spotty at best and usually zero. There may be coverage higher up the east slope of Ritter and the Minarets (cell signals are mostly line-of-sight) if the site on Mammoth Mtn is set up for a 360 degree signal. Coverage at Lake Mary is good...terrain is the big thing.

I've been away for several days. Had my head buried in work including a trip to Seattle.
CyDuke posted a very good link a few days ago.
"David" spent several days in the Minarets/Ritter/Banner area alone and with a friend in mid August this year
The 2nd photo on the site is his topo map.

His base camp was at the site above Ediza.
Besides the excellent high definition photos of several aspects of the range there is useful information.
Routes he/they covered
First: Solo Ediza->Iceberg->Cecile
then ascended South Notch. Climbed NW ridge of Kehrlein Minaret. He has many photos of Amphitheater Lake (which he thinks is un-named and calls "alpine" lake) and East face of Adams, back side of Ken and return via South Notch. The ruggedness of the area, especially the E Face of Adams is clear (Secor has no routes listed for E Face of Adams)

We can consider South Notch east side and NW route on Kerhlein covered. Note that he needed his crampons on the South Notch glacier.

His second outing was with friend and they climbed Ritter via SE Glacier. He also has a photo of another climber descending the glacier.
We can consider Ritter SE glacier covered.

Third trip, also with friend, was a round trip around Nydiver lakes towards NE side of Banner. A lot of XC travel but no climbing.

His fourth, also solo: Attempted the Central Chute on Clyde Minaret. Approached via Cecile Lake and climbed about 4 pitches before retreating from a 5th class section.
We can consider the traverse from Cecile Lake to beneath the N Face of Clyde Minaret covered. There's still a considerable distance from there to Cragman's furthest south excursion along the same giant ledge system.

This helps us eliminate (at least for the first pass) a lot of difficult ground. His notes contain a lot of detail and we can assume they didn't come across anything suspicious.

These are excellent reference photos, especially for the snow/ice conditions a month after Matt's disappearance.
He might be contacted to see if he can be of any help with information about Matt

High Traverse - thank you for reposting that link to photos. What a great reference they are!

Cyduke - thank you for posting that link.

Will someone be contacting the photographer to see if he noticed anything unusual?

Here's an update on the Mammoth Lakes missing person investigation. I just got back after being out of town for over one week. Detective Hornbeck finally located Morales. He didn't have any valuable information, but believed that if he reviewed the missing pages, that could trigger his memory. This information has been provided to Jill and Tiffany who will follow-up with Morales.

Detective Hornbeck has been in contact with the Bethlehem Sergeant who is handling their missing person investigation. All of our reports and files have been sent to him. They will be exchanging any information they discover.

Hornbeck was also able to access Matt's work e-mails. Nothing of value was there. It was all work related.

Thanks for the update, Chief Watson! I'm glad Tiffany and Jill will be able to follow up with Morales.

It's great that your department and the Bethlehem police department will be sharing all info in their respective missing persons cases.

Regarding Matt's email accounts, I hope his Hotmail account proves more fruitful.

I also hope that details of Matt's work emails can be provided to the family. Because Matt didn't have a smartphone and apparently send all email from the Mammoth library, even the timing of the emails he sent can contribute to a detailed picture of his habits while in Mammoth and especially to an understanding of what he did in the last few days before July 17th.

ctadlock....Thank you for all of your efforts and report! This will definitely close in the search area.

High Traverse...Thank you for the photos and deductive reasoning. I agree the family should try to contact the photographer.

Dan Watson...thank you for your follow through! Knowing that every rock has been turned over and every effort to find Matt has been made will bring peace to those who are missing him.

The community is holding a fund raiser to help in the search efforts. We haven't given up hope. Please know that all of the searchers' time, energy and knowledge of climbing and teamwork have not gone unnoticed. You all are an amazing group of people. Thank you for trying!

Sorry I have been gone a while. I got way behind in my personal and business life.

I came across this in the mammoth mountain forum tonight and thought I would share:

I like this and the idea behind the form. We will use it I am sure.

At some point down the line maybe we can figure out a way to get the word out on this. Maybe a non profit or something?

Matt is very likely in the backcountry and that's where the physical search is focused. There's a collection of scenarios in this thread that place Matt elsewhere. All are agreed to be very unlikely, but added together there's a greater (but still very small) probability that Matt isn't in the backcountry.

Has family formally entered Matt onto various US and Canadian databases in case law enforcement, a hospital, or the public recognizes him? I think some are run by law enforcement and others as private websites. Now that Bethlehem PD and MLPD have missing person reports, it may be easier to obtain a database entry. Just a thought...

Split Pants...great form! At least something good can come of Matt's disappearance.

Kenish...if we only had more of a clue as to where he was heading. It's a shame Morales' couldn't remember anything.

The school email didn't have any information, so lets hope authorities are trying to get into the Hotmail account. That is all we have left from the technology point of view.

There is a t-shirt fund raiser, along with others, to help with search and rescue efforts. Since SAR is all volunteer work, maybe the family could contact a group that would work for pay to search for Matt. Does one even exist? Time is of the essence. (Sorry if this was already discussed)

Hi SplitPants,

This forum was the first place I posted it after finishing it
but unfortunately no one noticed it and went down the list every fast.
I am hoping a Supertopo Moderator would place it somewhere on
this site so folks can access it, we have it pinned for the
moment on HST but it will be in our "Announcements" section
permanently for all members and non members to download it.
Hopefully we will be able to avoid situations like Larry's and
Matthew's in the future or at the least bring a quicker resolution
to all involved.
Please take advantage of it!


PS I am aware of my misspelling and that the number 2 is
missing off the Yosemite Dispatches Phone Number, but we
are having some technical difficulties which makes correcting
these not possible at this moment.

How about using some of t-shirt fundraiser money to hire the retired detective from Mammoth who works with his dog, Paul Dostie......mentioned in visions and dreams thread.....

Also - I sent Find Matt Greene poster to 3 Chambers of Commerce and got this reply today:
**//Mammoth Lakes Chamber of Commerce

Yes, I will include it in our weekly email blast which reaches 1,000 people.//

I haven't received a reply from Mariposa Chamber (Yosemite) or Minden, NV.
Any other suggestions of places to send it? I mentioned that we (you) are looking for someone who may have spoken to Matt close to July 16th that might have an idea where he went on the 17th.

I contacted Harv Galic from Stanford who wrote about the Rettenbachers, a couple who died climbing Banner Mtn in the 1930s, and who were buried near by.....part of his response as follows:

Wendy, I am painfully aware of Matt's disappearance. I came back from
the Sierra yesterday, and I can tell you that the 'missing' posters
are everywhere: at trailheads, national park's enter/exit stations,
forest service ranger station, etc. Actually, I was climbing in the
Minarets (which would be an area of high interest to Matt, and close
to his last known location) in the last week of July. At that time
Matt's disappearance was not yet known, but I didn't see anything
suspicious. However, that means nothing. Even if hundreds of people
were to comb the Minarets, they could still easily miss finding any

For the sake of family and friends, I wish there is a closure to
Matthew's case, and soon. However, the first snow may come to the
Ritter Range and nearby high mountains as soon as this weekend.

Pacarockhound...Thank you for your suggestions. Matt's family, who checks in with this forum, would need to decide how they want to spend the money. I'm sure they will see this, so thank you.

Great job sending out the flyers to everyone! The more people who know, the better! Perhaps someone else from the area could suggest other places to send the flyer. I am not from the area.

Please send Harv a big thank you for his report and words of wisdom. I realize the odds are against Matt. All we can do is pray for a miracle!

If anyone else has any other suggestions, please chime in.

Will anyone be hiking in the area this weekend?

Sep 19, 2013 - 07:02pm PT
So far ...

Still nothing. Nada, zero.

The guy vanished into thin air.

No one has a clue where he really went ultimately.

Still, .... just tons of guesses .......

Without quibbling on methodology this seems a very large number.

An astounding 2,300 Americans are reported missing every day, including both adults and children.

I never tell anybody where I'm going, but I figure my car being parked in a certain place would tip them off, if I was dead or whatever nearby.

Kenish and ZBrown

You now have me thinking about missing persons data bases....I hope Matt is on all of them.

Found the info about number of Missing Persons and details about searches interesting. Thanks for sharing that ZBrown.
