[2000 and Before]
Use the links to previous bloom year data directly above to search for bloom reports at a particular location to better fit a recent flower visit. NOTE: As of March 11, 2016, flower bloom is about 7-10 days later than 2015, or about 2-3 weeks early compared to the 1980s and 1990s.
I am currently spending time hiking and making plant lists for those trails and cross country routes that aren't well represented in the Columbia River and Klickitat River Gorges this season, so if you don't see your favorite hike here, please check the lists from previous years above to see what you'd see along those hikes. Comprehensive plant lists for a number of hikes in the Columbia River Gorge (Look under the state and county they are found in.) can be found at http://science.halleyhosting.com/nature/bloomtime/lists/plantlists.html
