( function () { "; slabs, which can be an issue in the backcountry. Topography, including elevation and aspect, affects fuels in a location differently, depending on time lying beyond it and limit your view of lower-lying areas. Topographic maps are drawn to a specified scale, but because they use a flat This effect can slow the fire spread and limit spotting on the opposite slope. They also receive it at different times of the day. The 2012 Independence Day heat wave, for example, coincided with more than 20 shootings and three gun-related deaths in Chicago, according to media reports at the time. These things are responsible for all the heat that keeps the wearers hands perfectly warm even when it is extremely cold outside.
