The beaver dam, almost a kilo­me­ter long, is so impres­sive that it can even be seen on satel­lite images. The beavers in Canada’s Wood Buf­fa­lo Nation­al Park have been hard at work for decades, and their tree plant­i­ng labor has paid off. Fur­ry archi­tects have cre­at­ed the world’s largest beaver dam.

The dam, which is about a kilo­me­ter long, is so mas­sive that it even appears on satel­lite images. It remained hid­den in the Alber­ta wilder­ness until 2007, when a researcher spot­ted the dam while look­ing at Google Earth. The beavers are cur­rent­ly build­ing new dams near­by which, when con­nect­ed to the main struc­ture, can add over 100 meters to the total length.

Beavers are one of the few species capa­ble of cre­at­ing dams large enough to be seen from space. Toothy crea­tures are won­der­ful envi­ron­men­tal engi­neers. Their dams redi­rect flows and even change entire ecosys­tems. These cre­ations are designed to be extreme­ly durable and are bar­ri­ers that form pools and act as pro­tec­tive moats. Dams are able to pro­tect beavers from preda­tors such as wolves and bears.


It is like­ly that beavers began work­ing on the dam in Alber­ta some­time in the 1970s, mak­ing it a mul­ti-gen­er­a­tional archi­tec­tur­al project. A thick lay­er with earth, branch­es, stones and branch­es is cov­ered with a lay­er of grass, which indi­cates a fair­ly long exis­tence of the struc­ture. The dam extends across a remote area of ​​wet­lands that pro­vides the crea­tures with ample fresh water and an abun­dance of build­ing mate­ri­als. Due to the iso­lat­ed loca­tion, it is dif­fi­cult for a curi­ous per­son to reach this place and dis­turb the beavers.
