Thanks. I have always loved Sioux Quartzite as it as close to indestructible as you can get. We have even gotten batches of 140 year old Sioux Quartzite road setts to use in landscaping. Some from the old Jobber's Canyon area that was ripped up in Omaha and some from Lake Street in Minneapolis. They made poor roads as the quartzite doesn't break down and get rough like granite, but will stay slick forever. One of these pictures is of probably the last remaining Sioux Quartzite section of street in the Jobbers' Canyon area of Omaha. Also old houses and stores around here were built from it. Very tough to work with as it is incredibly hard, it is used instead of diamond in some applications for industrial grinding and abrasives. One of these pictures is a load of tumbled quartzite stones in my truck used in mills to pulverize products, we plan to make a cobblestone landscape area with them.
Nice photos and info, Westfork!
