I will only focus on signs to assess the quality of a placed ice screw. There are many factors that influence the outcome like the location, temperature, ... but they deserve an answer of their own. The most important thing is, that the screw is placed all the way in solid ice. On the surface you can judge this easily. The deeper parts are assessed by what ...

Those types of glasses do not provide adequate protection from sunlight, especially in areas with lots of reflective surfaces (desert, snow) and at high elevations where there's more UV radiation due to the thinner atmosphere above you. What you want are either wrap-around glasses which don't let light in the sides, or particular glasses called "glacier ...

These are generally known as glacier glasses. They are rated as Category 4 on the CE scale and you aren't supposed to drive while wearing them. Sunglasses in Category 4 only transmit 4-8% of available visible light. Hidalogos sunglass guide has a very complete list of the different factors in choosing sunglasses. Category 4 come in a wider range of ...

Good Ice Sounds obvious, but that's the answer, you need to learn how to identify good solid ice for all your screw placements. The best ice is the thickest ice you can find, so you can place your longest screws; clear and blue will be the most solid, while the worst ice is cloudy or brown, full of bubbles (aerated) and 'crunches' when you poke it, or has ...

The basic idea of polarizing glasses is not to block all light, it's to block light that undergoes a glancing reflection, such as sunlight coming to your eye off of water or snow from near the horizon. The initially unpolarized light becomes highly polarized by this type of reflection, so by eliminating it, you make it easier to see and be comfortable ...

Addition to ShemSeger's answer, from way back in my mind: A concave spot in the ice is stronger than a convex spot, given equal ice quality. The ice should be deeper than the screw is long, so the screw doesn't push the ice away from the rock.

Generally speaking I agree with the sentiment that carrying a handgun is not necessary and more likely to get you into trouble than out of it, and I wouldn't suggest it was the right approach, however for the sake of a rounded argument... I have read & watched several guides on bear encounters, including a mandatory video before hiking in Canada's ...

The answers all correct, but the main questions is, Does unique Polarized glasses protect from UV rays? Yes...up to some extent (some percentage).That is, when polarized glasses block the horizontally polarized light from SUN, It also blocks the UV rays which are horizontally polarized. So one can protect from UV rays by using Polarized glasses up to some ...

To say that there is nothing that would provide a reason for carrying a firearm while hiking is completely false. There are numerous accounts where people have been killed by wildlife and hostile people. However, this doesn't just mean that anyone should just carry a firearm with them because they are scared. The likelihood of these situations happening is ...
