John, I'm glad you asked that as I had some information wrong.
For all the fire bans, they really mean all stoves have to have an off switch although they are worded differently. And I'm not surprised that someone said alky stoves were OK, some of the people in the office aren't even people who go into the backcountry and probably don't even know what an Alky stove is. Here's what I learned:
Roosevelt and Arapahoe NF do have Forest Service bans that apply to backcountry users and state:
"The use of petroleum-fueled stoves, lanterns or heating devices, provided that these devices meet the fire underwriter’s specifications for safety, is allowed."
That basically means an off switch.
Pike NF, where the first part of the CT is, does not have a fire ban of any kind.
Jefferson county, where segments 1,2,3 and maybe part of 4 (hard to tell where the county divide is on the maps I have) are, has a county wide fire ban including federal lands. BUT, they word the exception as:
"Any fires contained within liquid fueled or gas fueled stoves."
I asked them about it when the ban came out and they also said the stove has to have an off switch. But based on the wording, I can't see how they can cite you for using an alky stove. Well, they could, but it would probably be thrown out. But you can't legally use an Esbit stove which I think are even safer than alky stoves.
It was announced on the news that Park county was under a fire ban. Not exactly. What actually happened is all the fire districts in Park county have implemented their own fire bans. But these do not include federal lands. So in the National Forest in Park County, there are no restrictions at all.
