Jedi Posted January 2, 2004 Share Posted January 2, 2004 Planning on flying into the Ruth April 19th or so. Hopfully start climbing around the 21st. Will headlamps be needed for climbing at night? Roughly how many hours will they be needed? Jedi Quote Link to comment Share on other sites More sharing options...
willstrickland Posted January 2, 2004 Share Posted January 2, 2004 Yes, unless you time the moon phases right and there's no clouds. You'll have around 18 hours of sun above the horizon, probably 20+hrs of usable light, depending on the aspect of the mtn, cloud cover, etc. One thing to keep in mind is that if you aren't using something like a Petzl Arctic where you can keep the battery inside your jacket, the batt life is going to be much reduced due to the cold.

Jedi Posted January 2, 2004 Author Share Posted January 2, 2004 20 hrs, eh. Guessing from 10:30pm to 2:30am when it is fully dark. We will be on the western side of the mountain. Full moon will be April 5th and a new moon (no moonlight) is Apr 19th. Not is our favor . Good point about the batteries not lasting in the cold.

chris_w Posted January 2, 2004 Share Posted January 2, 2004 On May 1st I started the hike into the Kahiltna Glacier and took a headlamp, but never used it. We were moving during the daytime 8am-6pm and didn't do any moving\climbing at night. If you are planning some long pushes, I would take along at least a tika. I would also suggest getting the lithium-ion batteries. They are more pricey but have an operating temp down to -40 degrees. My CD player lasted 3-4 times longer on them in the cold vs standard batteries. chris Quote Link to comment Share on other sites More sharing options...
Dutch Posted January 2, 2004 Share Posted January 2, 2004 april in Alaska is like the rest of the country when it comes to day and night, you will be there in time for Break up, meaning lots of melting ice in the lowlands and plenty of mud Quote Link to comment Share on other sites More sharing options...
snoboy Posted January 3, 2004 Share Posted January 3, 2004 I would take along at least a tika. I would also suggest getting the lithium-ion batteries. I have been unable to find AAA Lithiums, only AA. Do you have a source??? Quote Link to comment Share on other sites More sharing options...
cj001f Posted January 5, 2004 Share Posted January 5, 2004 This probably should be posted more in Gear Critic, but.... has anyone tried the new BD Soliras w/Li-Ion battery? Quote Link to comment Share on other sites More sharing options...
DPS Posted January 5, 2004 Share Posted January 5, 2004 Lithium are reportedly not available as AAA. I use my Petzel Micro with litum AAs in winter rather than my Tikka for that reaon. Quote Link to comment Share on other sites More sharing options...
