Question	—	A method to retrieve a carabiner I saw this a few times, years ago I met some guys who were top roping next to us in Jackson Falls, IL 25 years ago who showed us a method of retrieving your top carabiner(s) when you were done top roping. They attached the rope to the 'biner in a strange way AND I seem to remember some para-cord be... (more)	—	over 8 years ago
Answer	—	A: What are the wall-cleaners in climbing called? What equipment/gear do they use? We used to call them 'wall sweepers' This is a wall that isn't climbed much. You can see in the video there are some fresh bolts that have been put in and few old ones. They are just using 'slings and carabiners' on their harnesses. They might have some cams or some nuts. I did not see any on th... (more)	—	over 8 years ago
Answer	—	A: What is the safest and most effective additive to keep drinking water from freezing? Electrolytes You can use an electrolyte solution in your water. Many do this for obvious other reasons but it will reduce the freezing point in the water. I'm sure you've seen the various powders at health food or supplement stores.

Answer	—	A: Is there any way to dispose of liquid fuel? Here are a few methods If you have a lawnmower or weed eater you can dilute your gas by about 5% to 10% with it and burn it off that way, even if the fuel is 'bad'.

Question	—	In kayaking how would you escape an underwater whirlpool current if you were trapped in one? In kayaking I've heard a term called the 'washing machine'.

Question	—	Blisters on small of back I went hiking with a friend a few years ago who had adjusted his new 90 liter pack to sit pretty high up on him. As a result he managed to create two very large blisters right above his buttocks. They popped and looked extra-ordinarily painful. He really suffered that weekend. My question is, wha...

Question	—	Under what circumstances would you not use a recently planted ice screw? I've done a lot of bouldering, sport climbing and some aiding. Awhile back I went ice climbing with some guys for about a week. I didn't participate much simply because I didn't feel the confidence I normally do in the equipment. Particularly ice screws. I asked the question, "Under what circumst... (more)	—	almost 9 years ago
