About this map

Sycan Marsh dominates this landscape, a significant wetland environment in Lake County recorded during the mid-1980s. The map illustrates a high-elevation basin where the Sycan River and Shake Creek converge, feeding into the marshlands before the river continues its course southward. Human presence is marked by the Brattain Ranch and several stock ponds, reflecting the area's long-standing ranching history within the Fremont National Forest.

Topographic features like Brattain Ridge and Sycan Butte frame the basin, while the Old Indian Treaty Boundary provides a vital historical marker of land division. This survey is particularly useful for understanding the water management of the era, showing various weirs and Steel Tower Trans Lines that cross the eastern slopes of the ridge. Smaller waterways like Chocktoot Creek and North Fork Creek drain the higher timbered ground into the marshy flats below.
