Career After his studies and years of research at the University of Amsterdam, van der Hammen arrived in Bogotá in 1951.

Van der Hammen analysed the Bogotá savanna and concluded a great lake (Lake Humboldt) was present there around 60,000 years BP, covering present-day Bogotá, Soacha, Funza, Mosquera, Madrid, Cota, Chía and Cajicá. Lake Humboldt on the Bogotá savanna around 60,000 years BP Van der Hammen has contributed greatly to the understanding of the geology of the Bogotá savanna and surrounding areas. He has worked with Gonzalo Correal Urrego towards an understanding of the prehistoric sites, as El Abra, Tequendama and Tibitó in central Colombia and has defined and described various geological formations, such as the Marichuela,Montoya & Reyes, 2005, p.65 Tunjuelo,Montoya & Reyes, 2005, p.71 and Subachoque Formations.Montoya & Reyes, 2005, p.69 His paleobotanical background proved valuable in dating the continental Cacho Formation.Montoya & Reyes, 2005, p.57

In 2000, a natural reserve in the north of Bogotá bordering Chía and Cota, Thomas van der Hammen Natural Reserve, was named after the naturalist. The mayor of Bogotá, Enrique Peñalosa, who ran twice for the Green Party, allowed the construction of homes in the reserve, leading to protests by residents.
