The Maasai Livestock Attack Site sits in the Tsavo region of Kenya, approximately at coordinates -2.7°, 37.4° — the same sprawling wilderness that made headlines in 1898 when two lions killed dozens of railway workers. Today, this broad savannah landscape is shared uneasily between Maasai pastoralists and a recovering lion population, making human-wildlife conflict an ongoing reality rather than a historical footnote. In the S15E02 episode of Expedition Unknown, Gates traveled roughly 30 miles with Big Life Foundation rangers to examine a freshly killed sheep belonging to Maasai livestock owner Ntawuasa Meeli, investigating whether a collared lion known as Osunash — and a suspected partner — were responsible for a string of livestock killings echoing the infamous Tsavo attacks. The site itself is not a fixed landmark but rather a working pastoral landscape, where the Maasai have herded cattle, goats, and sheep for generations. It serves as a vivid, present-day reminder that the tension between lions and humans in Tsavo did not end with Colonel Patterson's rifle.
The original Tsavo man-eating lion attacks terrorize workers building the Uganda Railway bridge over the Tsavo River, eventually killing an estimated number of workers before Colonel Patterson shoots both lions.
Maasai pastoralists continue semi-nomadic livestock herding throughout the Tsavo region, sustaining centuries-old traditions amid growing human-wildlife pressure.

Human-wildlife conflict in the Tsavo region is not a relic of the Victorian era — it is an active conservation and humanitarian challenge. As Kenya's population grows and agricultural and pastoral lands expand, lions and other large predators increasingly encounter livestock and people. Organizations like the Big Life Foundation work directly with Maasai communities to monitor predator behavior, compensate herders for losses, and collar individual lions to track movement patterns — the kind of fieldwork Gates observed firsthand in S15E02.
The Maasai themselves have a complex, centuries-old relationship with lions. Traditionally, killing a lion was a rite of passage for Maasai warriors, reflecting both the real danger lions posed to livestock and the cultural importance of demonstrating courage. Today, conservation efforts attempt to shift that dynamic by making lions more economically valuable alive — through tourism and compensation schemes — than dead, though the tension between wildlife preservation and pastoral livelihoods remains genuinely difficult to resolve.
The collared lion Osunash, investigated in the episode, represents both a conservation success story and a management challenge: collaring allows rangers to track individual animals and gather behavioral data, but a lion that repeatedly targets livestock creates pressure from herding communities that can be hard for conservationists to ignore. Whether Osunash's behavior constitutes a true pattern of aggression comparable to the 1898 Tsavo lions — or whether the parallels are more circumstantial — is the kind of question the episode raises without necessarily settling.
Gates' visit with Ntawuasa Meeli and the Big Life rangers offers a ground-level view of a challenge that wildlife managers, governments, and local communities across East Africa continue to negotiate. The episode does not present a definitive verdict on Osunash's guilt, appropriately reflecting the complexity of evidence in real-world wildlife investigations.
The Uganda Railway, which triggered the original 1898 Tsavo lion attacks, required laying approximately 660 miles of track secured by more than four million riveted bolts, according to the Expedition Unknown episode.
The railway project drew on a workforce of roughly 36,000 Indian workers brought in by the British, alongside local African laborers including members of the Maasai tribe.
Collaring individual lions allows conservationists to monitor their territory, hunting behavior, and interactions with human settlements — making animals like Osunash among the most closely watched lions in Kenya.
The Big Life Foundation operates across the Kenya-Tanzania borderlands, working with Maasai communities on anti-poaching efforts and human-wildlife coexistence programs.
The Tsavo region is generally accessible to visitors through Tsavo East and Tsavo West National Parks, which together form one of Kenya's largest protected areas. Independent travel to specific pastoral areas outside park boundaries — such as the Maasai grazing lands where this investigation took place — would typically require local guides and coordination with community leaders; check current travel advisories and consult reputable operators before planning a visit.
Voi, Kenya, is the nearest significant town and a common gateway to Tsavo East National Park, approximately 30–40 miles from the broader Tsavo investigation area.
The dry seasons — roughly January through March and July through October — are generally considered the best times to visit the Tsavo region, when wildlife is easier to spot near water sources and road conditions are more reliable.
Tsavo, Kenya
Tsavo, Kenya is the broader region encompassing the 1898 man-eating lion attacks that form the historical backdrop for Gates' entire S15E02 investigation.
Tsavo River
The Tsavo River was the specific site of Colonel Patterson's railway bridge project in 1898, directly tied to the original lion attacks Gates investigates in the same episode.
Voi
Voi serves as the nearest gateway town to the Tsavo investigation area and likely a base of operations for Gates and the Big Life Foundation rangers during filming.
South Africa (Kruger National Park region)
South Africa's Kruger National Park region represents a parallel case of ongoing human-wildlife conflict involving lions and large predators — a thematic companion to the Tsavo livestock investigations.
