In this installment of Sasquatch Tracks, the team reunites after a short hiatus to remember the life and work of a pair of icons in the field of anthropology, with the passing of Dr. Jeffrey Meldrum and Dr. Jane Goodall.

Dr. Jane Morris Goodall, renowned primatologist, ethologist, and conservationist, dedicated her life to expanding humanity’s understanding of the natural world and its profound interconnections. Dr. Jane Goodall was not only as a scientist but a humanitarian and moral leader, whose legacy endures in every forest preserved, every animal protected, and every young mind awakened to wonder. Her passing marks the end of an extraordinary era in science and environmental stewardship.

Dr. Jeffrey “Jeff” Meldrum (1958–2025) was a renowned American anthropologist and professor at Idaho State University, best known for his work on primate locomotion, foot morphology, and the evolution of human bipedalism. At Idaho State, Meldrum taught anatomy, evolution, and primatology and conducted research into evolutionary morphology, with special emphasis on how the foot evolved to support upright walking in hominins.

However, Meldrum was best known as one of the most prominent scientists to engage seriously with the Bigfoot (Sasquatch) topic, publishing Sasquatch: Legend Meets Science and curating a large collection of footprint casts—while remaining committed to applying scientific rigor to controversial claims, in work that drew both admiration and critique as he straddled the boundary between mainstream anthropology and cryptozoology. Dr. Meldrum passed away on September 10, 2025, following a brief battle with brain cancer at age 67.

We celebrate the life, and discuss the work of these two great luminaries in science, on this very special episode of Sasquatch Tracks.

In this installment of Sasquatch Tracks, the team is joined by David Zigan, a veteran investigator with over two decades of experience as a certified peace officer in Georgia, currently working in a Crime Scene Investigations Unit near Atlanta. A graduate of the National Forensic Academy, Zigan holds certifications in latent fingerprint examination and crime scene reconstruction, and has testified as an expert witness in numerous criminal cases. His forensic specialties include bloodstain pattern analysis, shooting incident reconstruction, and advanced fingerprint processing, which he has also taught as an adjunct instructor at the academy.

Now turning his attention to Bigfoot research, Zigan brings a scientific rigor rarely seen in the field. By applying his forensic background—particularly in dermal ridge analysis and evidence handling—he seeks to elevate the credibility of Sasquatch investigations. Through education and methodical analysis of physical evidence such as footprint casts, Zigan is helping bridge the gap between mainstream forensic science and cryptozoological inquiry.

In this installment of Sasquatch Tracks, the team presents an update on the well-attended annual Ohio Bigfoot Conference, before taking a deep-dive into one of the most promising new analytical endeavors related to relict hominoid research, The Sasquatch Data Project.

Joining us to discuss this ambitious effort is Terrestrial, the nom de plume of the data scientist behind The Sasquatch Data Project who in the past worked on NASA's Dawn Mission related to the study of the dwarf planet Ceres. Terrestrial has a Bachelor of Science in Earth & Atmospheric Sciences from the Georgia Institute of Technology and is currently pursuing a Blue Ridge Naturalist certification. According to her website, while working as an undergrad at Georgia Tech, she played an integral role in categorizing, identifying, and measuring ground-ice features on Ceres for NASA’s Dawn Mission, and first-authored a paper published in JGR: Planets, in addition to co-authoring several papers while working on this mission.

Terrestrial tells us her interest in Sasquatch began at the early age of 5 and has only grown since. In 2023 she decided to retire as a professional Twitch gaming live-streamer and devote her time into creating the ultimate data resource to aid in the research of North America’s soon-to-be-known great ape, the Sasquatch.
