The Great Square of Colorado Challenge!


This cache is at the posted coordinates. You must read the page below for the requirements to log this cache.

What is the challenge?

In order to log this cache, you must do the following:

1.) Log the caches at each of the four corners of Colorado

2.) Log the benchmarks at each of the four corners of Colorado (with one exception, see below)

3.) Sign the logbook!

Though not a requirement for logging, if you would like to post pictures of yourself at each of the corners, and pictures of the benchmarks, these would be most welcome.


The caches and benchmarks at each of the corners are listed below. The cache name is followed by the Geocaching.com waypoint. For benchmarks, the benchmark designation (name) is followed by the Permanent Identifier (PID), a two-letter code followed by a four digit number.

Colorado/Nebraska
Cache: Where the Handle Meets the Pan, [GCB989]
Benchmark: Northeast Corner Colorado Reset, [MN0401]

Colorado/Wyoming/Utah
Cache: UCOLWY, [GCGEEC]
Benchmark: GLO 28 CO UT WY, [MQ0481]

Colorado/Utah/Arizona/New Mexico
Cache: Four Corners Monument, [GC6A98]
Benchmark: CO UT AZ NM, [AD9256]

Colorado/Oklahoma/Kansas
Cache: Coloklankan, [GC936F]
Benchmark: Boundary Mon CO KS OK, [GL1538]

At the Colorado/Oklahoma/Kansas corner, the benchmark is under a bolted manhole cover and is likely not available for viewing. The old manhole cover at this location, Designation: Boundary Mon CO KS OK Punch Mk, [AA7182], was a benchmark at one time, but was recently stolen. This new manhole cover is not the benchmark, but provides access to it.


Other rules:

Your previous finds of any of the caches or benchmarks will count.

If you own the cache at one of the corners, your hide will count as a find for that cache for the purposes of this challenge.

You may have others with you when you log this cache, but only those who have fulfilled all the criteria for this cache will be allowed to log it as a find.

When you log your find, please include the date which you found each cache/benchmark.

Have fun!!

Another caching day with FeartheFish. Early morning caches on Mt. Falcon and surrounding area. Signed this one; don't know if I will ever meet it. TFTC!

12:16 PM We are here from Dallas for our typical August vacation in Divide in order to skip the Texas heat for a couple of weeks.

Today we drove to Denver mainly for the Colorado DeLorme and Great Square of Colorado challenges, plus a rare D/T combo involving a tree climb instead of hanging off a cliff.

We are capping it off with a geocache event to celebrate RPieperCO's 4 year geocaching anniversary.

We had a nice hike to the GZ. My GPS indicated I was 27 feet WSW of the cache when I found it. Not bad. FWIW, my averaged reading was N847 W493 (averaged a few minutes to 50% sample confidence).

I was really excited to sign the log on this challenge cache - below my friend WingsAndTales. The NW corner of Colorado was definitely the hardest and the most memorable. (I picked up a clean tire puncture that didn't go low until the next morning - and I got it patched within an hour at the tire store a few blocks from our hotel in Vernal, UT. How lucky is that?!)

Thanks, Me & Bucky, for the challenge cache, the hike to the GZ, and - last but not least - the memories.

I just got back from a meandering trip to finish up Colorado DeLorme requirements (6 sectors in a checkerboard pattern in the southwest corner), New Mexico DeLorme (012 & 014), and the oldest cache in Utah. I also visited my final corner of Colorado - the southwest corner.

The southeast corner was an easy diversion on a meandering trip home to Dallas from Albuquerque. The northeast corner was a fun little weekend trip following a business meeting in Denver.

I visited the northwest corner last summer. Definitely the hardest. Five days ago on 7 June, I visited 4 corners and logged the benchmark.
(The virtual cache Cache: Four Corners Monument, [GC6A98] is archived and locked.)

I know I've been to Mt. Falcon park. For the life of me, however, I can't find any notes that indicate I signed the log. I plan to get over there and do that in mid-August.

My wife reminded me that she had been with me for every county in Colorado. I'll have to revisit 4 Corners with her so she can claim visiting every corner benchmark, too.

Links to geocache logs and found dates (same dates for benchmarks) are included below. Let me know if you have questions. Thanks!

I don't qualify for this one yet (missing the NW corner) but we were riding up here & decided I might as well sign the log with the hopes of getting there someday. I actually only got the east corners this year.

And the first shall be last...(that's not how the phrase usually goes, is it?)...

My first visit to a corner was back in the 80s, when I went to 4 Corners with my family. But, of course, there was no geocaching then, and I play the game pretty truthfully, so that doesn't count.

Bug Ranger made me aware of this challenge about a year ago, and I logged the NE corner on a trip with my non-caching husband (a patient man, he is) on 5/10/16.

BR and I signed the actual log of this cache during a visit to Falcon Park on 7/28/16...now we were committed to the process...

So, Bug Ranger and I got gonzo about this, and took a trip to the SE corner, tagging that on 9/23/16, in the process also filling out the eastern counties and De Lorme pages for Colorado.

That trip went so well that we did the same thing for the western part of the state, scoring the NW corner on 10/4/16. Wow, is this one memorable--NOT a trivial drive in there; it pushed my Outback to its limits.

But...that 4 Corners? BR already had that one, and it was out of the way. Fortunately, my husband and I had long planned a trip to Zion and Bryce, so we passed right through this one today, 10/16/16, and this time I tagged it for geocaching purposes--got the benchmark, anyway. My husband took a picture of me at the monument, since there's no longer a virtual or other cache at the site, but I was there.

So today I finished up this challenge. Oh, and I also grabbed my last county and my last De Lorme page--a red-letter day for sure. What a state Colorado is!

And, what will I do NEXT summer?!

What a Challenge! This took more than four years to complete, and a lot of driving.
I began this Challenge on 4/4/12, with a photo of me at the Four Corners, while travelling with Diaphi. We tagged "Benchmark AD9256" as well. Really sad that the Four Corners Virtual is gone.
The second corner, Where the Handle Meets the Pan, was attained on 4/01/2013, on the way to Kearney, NE, with Photolite, for a sandhill cranes viewing trip.
EstesLynne & I got the physical cache for this challenge on 7/28/16, on a hike around Mt Falcon.
Last month, EstesLynne & I did our first big caching-trip on the eastern side of Colorado, and we tagged the SE Corner, ColOklaKan, and the Benchmark, on 9/28/2016. We finally got the NW corner today, 10-4-16, while on a gonzo 5-day geo-road trip for DeLorme pages, counties, and of course, this corner. Finally, the Challenge is complete! TFTC!
