Arizona State University's Volcanology Field Trip to GUATEMALAJR's Journal Around Xela—Cerro Quemado and the Pumice Enema |
After a good breakfast at the hotel, we loaded up and headed south out of town to go to Pedro's house. The day was clear and warm so we had excellent views of Cerro Quemado and Santa María. We found the house without too much problem and apologized for not appearing last night. We paid him for a day's services. He was happy to receive it. We visited a couple of small quarries in the hummocks from the debris avalanche off of Cerro Quemado which are quarried for dimension stone. Our van managed to get stuck on a high rock in the road but with everyone out and pushing got it going again quickly. Then, we returned to the hotel for lunch. I managed to get out to an internet café for the first time in several days. The world is still out there. We regrouped at 2:30 and headed west out of town on Calle 4 to the pumice enema site at San Juan Ostuncalco. The pumice enema was named by Sam Bonis back in the 1970's. It is a series of quarries and roadcuts that expose the Atitlán III unit, particularly, the Los Chocoyos tuff. The quarries are now huge and provide excellent exposure of the pumice unit. Darkness fell before we could go to the road cuts I remember. Jonathan excavated a nice chunk of charcoal from a log buried in the ash flow. The individual tree rings were clearly visible. Several native women and children watched us with amusement. We drove back to Xela and got pretty lost in town. I saw parts of the city I had never seen before we finally got back to the hotel. I took a shower and then went to dinner with the group in the dining room. It was a merry time and a good meal. Unlike the other nights on the trip I was very tired so I just called it a night early and went to bed. |
