SALT LAKE CITY (AP) — A professional jumper has vowed not to leap anymore from cliffs inside national parks after he pleaded guilty to doing it twice in Zion National Park in Utah. Marshall Miller said Wednesday he will respect a law that prohibits BASE jumping in all national parks. Two people have died since 2013 while BASE jumping in Zion National Park. Officials say Miller made a wingsuit jump from an area called the Great White Throne that has been closed to visitors to avoid disturbances to an area used by nesting peregrine falcons. Miller said he’s made more than 5,000 jumps and it’s his love and passion.
