California has 15 peaks over 14,000 feet, the so-called "14ers". Previously, efforts to bag all the peaks were hampered by the fact that the second highest, Mount Williamson, was closed much of the year (July 16 - December 14) to protect Bighorn Sheep. Climbing Williamson, which is close to Tyndall, adds a few hours. Some record-seekers (Florine, McBride) chose to respect the closure, and climb only the 14 "legal" 14ers, while others (McBroom, Swartz) have ignored the rule, tagging all 15 peaks. However, the closure has recently been lifted.
