The six smokejumpers from a base in Redmond found the site Monday evening, when there was a rash of lightning strikes.
Jackson County sheriff's spokeswoman Andrea Carlson says the smokejumpers notified authorities, who hiked into the remote site in the Rogue River-Siskiyou National Forest. They seized two guns and more than 1,000 little pot plants.
Carlson says the site near the community of Applegate was being cultivated by growers for Mexican drug gangs, and it's been used before.
She says the smokejumpers saw some people but weren't sure whether they were pot growers, so no one was arrested.
The smokejumpers extinguished the fire after it burned less than an acre.
