The most prominent feature of Falkreath Hold is Lake Ilinalta.Lake Ilinalta is a major part of Skyrims Hydrosphere. It receives much of its water from the large amount of rain Falkreath Hold gets, as well as the constant runnoff from the surrounding mountain ranges. Lake Ilinalta drains into the White River which runs northeast through Skyrim, eventually draining into the ocean. The water is then evaporated off the ocean and eventually returns to Lake Ilinalta, thus completing the Hydrosphere. The White River is an example of a dendritic drainage patter, meaning it branches off into other smaller streams as it flows to the ocean.

Another notable geographic feature of Falkreath Hold is the forest that covers it. This thick pine forest makes Falkreath Hold a transport limited landscape, meaning that weathering here is slowed down by the amount of vegetation present.

While exploring the pine forest I noticed an example of root wedging. A few pine trees were growing out of a formation of rock. The growth of the trees roots will eventually lead to physical weathering on the rock.

Falkreath Hold is an important area to the people of Skyrim because it is a major source of fresh water, as well as lumber from the pine forest used in building homes and other structures.
