IIUC Half Dome is now a separate permit, issued via lottery.

Yosemite backcountry fires are permitted up to 9,600 feet, but do check about additional restrictions specific to very popular areas. I'm guessing such limits do exist, since easy wood gets stripped out pretty quickly in popular subalpine areas.

Last summer during fire season, fires were also banned below 6,000 feet, meaning there was a narrow legal zone between that and 9,600 feet. Had to parse our maps pretty carefully to stay legal.

Cheers,
