Here is the post on the INYO site:
Beginning June 28, and until further notice, the following restrictions will be in effect:
NO CAMPFIRES, briquette barbeques, or stove fires are allowed outside of designated developed recreation sites and specifically posted campsites or areas. A list of designated campgrounds and recreation sites is available at local Ranger Stations and Visitor Centers, and on the Inyo National Forest website, www.fs.usda.gov/inyo.
Persons with a valid California Campfire Permit (available free of charge at any Ranger Station or Visitor Center) are not exempt from the prohibitions but are allowed to use portable stoves or lanterns using gas, jellied petroleum, or pressurized liquid fuel.
NO FIREWORKS. It is prohibited to possess or discharge any fireworks.
NO SMOKING, except within an enclosed vehicle or building, a developed recreation site, or while stopped in an area at least three feet in diameter that is barren or cleared of all flammable material.
NO WELDING or operating an acetylene torch with open flames, except by permit.
NO USE OF EXPLOSIVES, except by permit.
Its a little vague, but it seems to maybe prohibit alcohol stoves. I called when I saw this.
