Married since 1975, Diane Z. and Arlen F. Chase are two of the most influential Maya archaeologists in the world, and the foremost experts on Caracol, one of the most significant ancient Maya cities.

Since their first dig in 1985, the Chases have become known for:

• Providing a nuanced picture of Caracol’s ancient landscape and people, including recognition of Caracol as a city of advanced urban planning, road systems and markets and a large non-elite population upending the notion of a strict Maya social hierarchy. In 1986 they discovered an inscription that told of Caracol’s military victory over Tikal in 562 AD, overturning the myth that Tikal was the most powerful Classic Period city and illustrating that Caracol was a major military and political power.
• Using airborne LiDAR (light detection and ranging) technology to uncover structures hidden for centuries under dense jungle, revolutionizing how archaeologists explore Maya sites. Their work from the 1980s-2000s revealed a web of interconnected roadways, proving that Caracol was a massive, urban and integrated city.
• Overturning outdated beliefs about the Maya, while providing new insights. Their archaeological work has shown that ancient Maya society was composed of many different social gradients, contrary to more simple two-class models. From the 1980s -2000, they and their team mapped numerous causeways (or roads) and thousands of agricultural terraces spread out across Caracol as well as hundreds of reservoirs in non-elite areas, proving that water, sacred to the Maya, was not controlled by the elite, as previously thought. The Chases’ son, Adrian Chase, also an archaeologist, found that Caracol had a decentralized water system and that residential groups had their own access. He is currently studying the urban structure of Caracol and changes in governance over time.
