Did you know? Mexico has more than one geographic center
Mexico has more than one geographic center.
I've often been asked, "Where's the center of Mexico?", and I've always deliberately fudged my reply, but is there a simple answer to this question? Well, perhaps not surprisingly, there isn't!
Several locations lay claim to being the center, but it's all a question of definition. Does center mean "the point where the minimum distance to the ocean in any direction is as large as possible" or does it mean "the center of mass of the country, located by complicated mathematics or by reproducing its outline on a sheet of cardboard and then balancing it on a pin"? But (I can already hear you cry), that doesn't take into account where the mountain ranges are - "Aren't they heavier than the flat coastal lowlands? Don't they affect the center of mass?". None of the above takes into account the uneven distribution of population in Mexico, either...
So, there has to be more than one answer to the original question, "Where's the center of Mexico?" According to the townsfolk of Tequisquiapan, a spa town in the state of Querétaro, their town is the center. They've even erected a monument to that effect with a plaque that clearly states "this is the geographic center of Mexico".
Despite the claims of Tequisquiapan, many Mexicans have claimed to me over the years that the true center is actually a point in Guanajuato state, very close to (or corresponding precisely with) the Cerro del Cubilete, the prominent steep-sided hill that rises above the interior plains between the cities of Silao and Guanajuato. I've never been clear on what basis this point qualifies for the "geographic center sweepstakes", but the hill certainly does boast a huge religious statue on its top, and is a regular destination for thousands of pilgrims.
Another alternative is offered by the government mapping and statistics organization, INEGI. Maps displayed when the option "Centro geográfico" is selected on one of its web-pages show that a point in Zacatecas is likely to be the center of mass of the country, with the precise location depending on whether only mainland points are used in the calculation, or whether islands are also included. Strictly speaking, the INEGI calculation is based on averaging the furthermost points of Mexico in the four cardinal directions, rather than on a true "center of mass" calculation or demonstration.
The true center of mass has been calculated, according to a brief text by Homero Adame Martínez in Mexico Desconocido (January 2000), to be yet another point in Zacatecas, just south of the village of Cañitas de Felipe Pescador. Most conveniently for all railroad lovers, this point is very close to where the tracks of two major railroads (from Mexico City to Saltillo and Ciudad Juarez respectively) diverge. Readers with a little time on their hands might like to construct their own cardboard cutout of Mexico to determine if the center of mass they determine corresponds with any of these versions. (Webmaster's note: if any readers do try this out during the month of October 2002, how about posting your reults on the General Forum.)Incidentally, Mr. Adame also relates how the city of Aguascalientes once laid claim to be the center, placing a plaque (sadly no longer there) to that effect on a post in the city's central plaza...
Well, having explored the issue of "Where's the geographic center of Mexico?", let's end with a related but much simpler to answer question: "What's on the opposite side of the globe to Mexico?" This is the point where you would eventually emerge if you were able to dig an unbelievably deep hole straight through the center (core) of the earth. If you began digging outside the National Palace in Mexico City, you'd emerge... in the middle of the Indian Ocean, relatively close to the tiny Cocos (Keeling) Islands.
