Here's the fire history. This Ponderosa Pine stump has 13 visible fire scars. Each ripple is where the tree was scared when a fire came along and burned the ground fuels that had built up sense the last fire.
Here's my educated guess on the age of the stump and frequency of natural fires. This pine was about 250 years old when it was cut about 40-50 years ago. During its lifetime it saw at least 13 forest fires. The fires were low intensity due to their frequency but just hot enough to leave a scar on the cat face (pitch face) created by the first fire it saw when it was a sapling sometime in the first half of the 1700s. The intervals between fires averaged about 15 years The last fire was probably about 1910 when wildfire suppression became effective in the US.
