Yosemite National Park has dismissed ranger and bat biologist Shannon "SJ" Joslin after the 35-year-old unfurled a 66-foot-wide transgender pride flag from El Capitan on 20 May. Joslin said the banner, which was taken down after roughly two hours, was meant to signal that national parks are safe for transgender people. Park officials said Joslin’s action violated demonstration rules and cited "unacceptable conduct" in the termination letter delivered last week. Joslin was part of a seven-person climbing party that included two other rangers, both now on administrative leave while the National Park Service reviews the incident. The National Park Service is working with the U.S. Justice Department to weigh administrative penalties for additional employees and potential criminal charges against visitors who helped stage the display. Yosemite, which logged more than four million visits last year, restricts protests to designated First Amendment areas. A day after the flag was hung, Acting Superintendent Ray McPadden imposed a rule barring banners larger than 15 square feet in areas classified as wilderness or potential wilderness—about 94 percent of the park. Spokesperson Rachel Pawlitz said the measure protects natural resources and visitor experience; advocates for Joslin contend the firing aims to silence federal workers amid broader Trump-era curbs on transgender rights.
