Evidence of Fire at Hartley
In the late 1939's about a 1000 7 foot holes were dug in Hartley Park by a federal work project. Fro
m all of these, the depths of soil layers was determined.
This soil texture survey described the surface humus layer of large areas of the park as "burned out", and areas of the forests as "sparse".
The Cloquet fire of 1918 probably burned out most of the area of what is now Hartley Park. No trees that we know of show evidence of that fire.
Below is some further evidence of fires in the park.
