He was there on the second phase of the dig for five months and went back for another 10 months of duty. John Rambo, a junior from Oklahoma, arrived in Israel in August 2007 and stayed seven months. "It was the adventure of a lifetime. We were put on jobs that not everyone got to do,” he said. During the time in Israel he said he had an opportunity to learn Hebrew and experience the culture. Brandon Nice, a junior from Indiana said the tunnel runs north and south and the walls follow a natural cavity in the bedrock. The tunnel measures more than 60 feet, but its ends are blocked with stones. He said he enjoyed the time the group had to visit other places in Israel, as well. "Jerusalem is such a mix of cultures, it was exciting to see them all together,” he said. Victor Vejil, a graduate student from Texas, arrived at the dig in September 2007 and returned in October. He said he stayed to help process the finds. "Looking at the pottery, seeing all the pictures and the special finds and getting direct input was tremendous,” he said. Mazar thinks only 5 percent of the tunnel has been uncovered. Students hope to return to the area.
