Morelos Archeological Site

Chalcatzingo is an ancient Olmec site (1,500 BC) an hour's drive from Tepoztlán, where I live. The Olmecs are the oldest known Mesoamerican civilization. A group of us went on an excursion there. Here is a link to a YouTube video about Olmec culture.

After walking in from the parking lot, we first examined the bas-reliefs carved into the rocks and protected with overhanging roofs.  We took a long hike up the mountain. After coming down, and before leaving, we investigated the pyramids at the site.

It turned out to be a very long and tiring but very rewarding day.

Bas-reliefs are carvings in the rock. Chilcatzingo is one of only two Olmec sites having these. They are unique and varied in content. Here is a slide show I made of them:

After looking at the bas-reliefs, we decided to take the trail to climb the mountain.

On the way from the area with the bas-reliefs to the beginning of the trail, we saw some interesting flora and fauna.

Climbing the Mountian

One member of our group had climbed the mountain before and guided us on the trail to the summit. It took us a grueling  two hours, given the heat and dryness, to get to the top. The trail was not difficult other than this, and the views were spectacular. We witnessed a lot of beautiful nature on the trail.

Chilcatzingo, Morelos, Mexico. We finally reached the top! Note the beautiful panorama of views (top). There is a cross (lower right), and here is a companion mountain (lower middle).  It's nice to take a rest and recharge (lower left). Photos by author

The trip down was by the same trail. Gravity helped, but we were so tired from the heat and struggle to get the to top that the descent was giddy.

The Pyramids

Before leaving the site, we checked out the rounded pyramids.

Between the two pyramids is a flat rectangular stone structure. I am guessing that it is the place where a speaker might stand to be heard by an audience sitting on the pyramids. When we stood there and clapped, the echo that came back from the pyramids was of a much higher pitch. Did the architects plan that? I think so.

Everyone in our group left Chalcatzingo exhausted but happy for the experience.

FYI: Here is a link to a news article about the recent return of an Olmec artifact to Mexico. It is now on display in Cuernavaca, but will eventually be housed at the Chalcatzingo site.

I will post them here with your name unless you ask to be anon.

I was fascinated by your sharing and enjoyed visiting Chalcatzingo vicariously, without the heat and the strenuous hike.The unusual bas-reliefs are beautiful. I appreciate that you offered this glimpse without asking for anything in return.


Thanks, Lasita or your kind comments. What I ask in return is that readers consider buying my self-published books listed at the end.



Enjoyed this article about what ancient people created. For me, although the creators of the reliefs and pyramids died long ago their spirit is still present.

--Alice Hesselrode

Thanks, Alice. Your spirit is strong in my life, too.



Thank you very much for the wonderful photos and descriptions. I truly appreciate your blog and sharing.

-- Delia

My pleasure, Delia. And thanks for your nice comment.



WOW, don, your report is very beautiful. Thank you. I have always had a soft spot for the Olmecs, since I was a teen in Germany. They are of an inter-racial origin is it said? Bridging Afrika? Thank you. Thank you.

--Leonore Alaniz

Thanks, Leonore. Yes, I put a lot of hard work into this one. Sorry, I can't answer your question of origins.



I very much enjoyed  your account and the description of the ascent...and descent of the mountain. I have never seen rounded pyramids before.  There is obviously some connection between Mexican and Egyptian pyramids... a shared ancient history that would be interesting to explore. A long hot and interesting climb to the top of the mountain.

--Maria Espinosa

Glad you enjoyed it, Maria!
