Jon Spenard (CSUSM; Project director)
Jon is Associate Professor of Anthropology at California State University San Marcos. He has been a member of numerous archaeological projects in Belize, Guatemala, and Mexico on which he studied ancient Maya ritual landmark use. Prior to starting the RiFRAP in 2018, Jon most recently studied the ritual caves and landmarks of the nearby Maya center of Pacbitun, a site with close ties to the Mountain Pine Ridge.

Mike Mirro (RiFRAP; Project Field Director, GIS Specialist, and Digital Archaeology; project co-founder)
Mike has worked on numerous cave archaeology projects  in Belize since 1996. He completed his Master’s research at Barton Creek Cave, one of the primary outlets draining the Mountain Pine Ridge. He currently works for the CRM firm, PaleoWest Archaeology in Southern California. For the RiFRAP, Mike is the project Jack-of-all trades, from digital modeling, and GIS, to expert climbing and mapping. Unfortunately, he’ll be on a research hiatus during the 2023 summer field season, but still supporting us from back home.
