Clover fire, while still a WFU

I came across a map, above, of the Clover fire on the Sequoia National Forest, while it was still a Wildland Fire Use (WFU) fire on June 18. On the north and west sides, it was mostly hemmed in by previous fires that burned 2-4 years previously. On the east and southeast sides was an old 64-year old burn, and there was no fire history on the southwest side. The black line east of the fire is the Kern River.

Yesterday the fire crossed the Kern River, crested the Sierras, and burned east toward Hwy. 395
