"So, Hebs, you can see here, through the hand lens, the equal proportions of orthoclase and plagioclase feldspars that make this boulder not a granite, but a quartz monzonite.""I see, Gee! And the much smaller proportion of quartz also indicates a monzonite."
(The hand lens is a very popular tool on hikes in our family. Picture taken up at Silver Lake, near Brighton, Big Cottonwood Canyon.)
I miss you guys so much, I almost jumped in the car and drove back to your house for two more weeks.
