当他在怀俄明大学读研究生时，UNH博士后研究员 Alex Garcia-Putnam 在秘鲁安第斯山脉发掘一个圆形广场，地点叫卡拉科马. 该遗址后来被证明是安第斯山脉北部已知最早的巨石圆形广场，也是美洲最早的此类建筑实例之一, according to a recent article in the journal Science Advances.
放射性碳年代测定法表明广场的最初建造大约在公元4世纪,750 years ago, 大约比埃及大金字塔早100年，与巨石阵同时出现. Garcia-Putnam and other researchers knew the plaza, measuring about 18 meters in diameter, existed before excavation began in 2018, but “we had no idea it was going to be that old,” he says. “It’s a very significant site.”

Now working as a bioarchaeologist in the anthropology department 也是UNH法医人类学鉴定和恢复实验室的联合主任, 加西亚-帕特南在卡拉夸马的工作包括教授本科生和监督部分挖掘工作. “This is definitely a team sport. 如果没有当地社区的支持和学生们的努力，我们不可能做到这一点.”
