Field Trip Report by Corinne January 27, 2007 Estrella Road
Barb Ballard met us at Hwy 68 and Estrella Rd on Sat. Jan. 27. A hiking group was also meeting there and that made for many people and vehicles.
We were fortunate in having Sue Griffith as our guest. She is a Professor of Geology in England and teaches via the Internet while in the USA.
We had six canines: Toby, Huck, Bailey and Lacey, and Marrs and Coco, 18 rock hounds and l0 vehicles.
After driving up a picturesque wash we parked on a clear and gravely area. And then scattered looking for perlite, chalcedony, and silicified banded rhyolite. Linda Chandler reminded us that perlite cools slowly, while obsidian cools quickly, and that the two are the same composition. Ruthie Montgomery, Barbara Wiggins and Barb Ballard found pieces of chalcedony with small bubbles of fire. Don Hughes found a hand sized chuck of chalcedony while on the scouting trip.
After socializing and having lunch Barb led the group to I-40 via Aztec and Shinarump Road.
Thanks for the good trip Barb
