Hello, It's red because of a rock used to surface the road called "clinker". More can be found on various webpages, and I'll quote them below: " Clinker, sometimes incorrectly referred to as scoria, is the baked red sandstone and shale that lie above a burned coal seam. These are literally "cooked rocks." Heated to high temperatures, oxygen combined with iron in the rock to form iron ixide, producing the bands of red rust color... ... Clinker is one of the best road surfacing materials and explains the red color of some highways... " Search Strategy: "red colored roads" on google: ://www.google.com/search?q=%22red+colored+roads%22 clinker road surfacing on google: ://www.google.com/search?q=clinker+road+surfacing Additional Links: Good picture of clinker surfacing on roads: http://www.bittsandbytes.org/Eastern_Montana/Clinker_Road.jpg Article on clinker: http://www.bittsandbytes.org/Subscribers/05_05_02.html Another article on clinker: http://www.mt.blm.gov/mcfo/clinker.html skermit-ga |
