30-Dec-2001 -- Well, I visited the confluence with my new wife. (We married on the 22nd of December.)

First, we tried to find a map that showed San Diamián, Guanajuato, but we were unsuccessful. I even asked some of the locals where we spent our honeymoon (in San Miguel de Allende), but they could not tell me where the town is located.

According to the maps we were able to obtain the closest town south of the confluence was Xoconoxtle which was about 8km away. We decided that going to San Marcos and approaching the confluence from the north was the best thing to do because the town was on the map and only 3km away.

We started at 12:30 p.m. from the outskirts of agricultural San Marcos. Right at the edge of town we began our trek over four massive hills that seemed to be carved by intense and brief storms. (Being a geologist I could tell that this was an arid, dry area that receives brief periods of these intense, erosive rains whose footprints are the dry, etched, boulder riddled river beds within ravines.) Between each of the hills the deep ravines proved very taxing as we tried to climb out of them. We had to deal with much cactus, thorny shrubbery (specially in the ravines), barbed wire fences, and rocky hillsides along the way. All this made for a longer trip than I thought it would be (We got back at 4:30 p.m.)

Unfortunately, the confluence was located within a ravine on the hillside. There was so much brush and cactus, that we could not get very close without risking falling on the steep hillside and ending up plucking thorns from our skins. Also, because of the steepness and narrowness of the ravine our receiver had trouble getting signals within the ravine. The closest reading we got was latitude 21 00' 05" N, longitude 101 00' 00" W. The general area of the confluence can be seen in picture #1. The ravine lies along the middle of the picture. The confluence probably lies just on the edge of the hill above the ravine.
