9:00 a.m.

Book Club members will meet and discuss the book Friday, September 1 at 9 a.m. in our lecture room. The life story of Georgie White Clark, adventurer, raconteur, and eccentric. Georgie first came to know the canyons of the Colorado River by swimming portions of them with a single companion. She subsequently hiked and rafted portions of the canyons, increasingly sharing her love of the Colorado River with friends and acquaintances. She established a guide service to support her own river trips, and in time became perhaps the canyons' best-known river guide. Georgie helped transform an adventurous sport available to only a few into a major tourist activity. She was eighty years old when she guided her last boatload of passengers down the Colorado. Westwood's biography shows us a woman who wasn't perfect, but who loved the Colorado River and its canyons and who made it her life. Our BTA Book club we showcase a new title each month with a lively discussion that meets on the first friday each month. Attendance at our once-a-month meetup is included with $12.50 daily admission if you're not already among our annual members, or don't have an AZ State Parks annual pass (and free, of course, to all who do).

11th Annual Butterfly Count Saturday September 9
8:30 a.m. meets in the Visitor Center
Love butterflies? Join Central Arizona Butterfly Association (CAZBA) members and volunteers Saturday, Sept. 9, for their 11th Annual Butterfly Count at the Arboretum. Modeled after annual Christmas Bird Counts, the once-a-year butterfly census coincides with peak populations, and is conducted within a 15-mile circle that encompasses the Arboretum as well as the Oak Flat campground seven miles East; with enough volunteers, teams will also canvass Queen Creek, the Arizona Trail - and Queen Valley. The goal is a comprehensive one-day tally of as many butterfly species and individuals as can be seen within that perimeter, a 'snap-shot' of popu-lation dynamics that can be monitored over the years. One great thing about butterflies? They sleep in! Well, at least they get active a few hours later than dawn-chorusing birds... so butterfly counting starts at a leisurely hour of 8:30 a.m. when participants meet in the Arboretum visitors center to divide into teams. Another fun aspect of this count is that participants re-group for an lunch meetup – last year it was at Jade Grill restaurant in Superior, where Chef Lucy Wing served a tasty buffet of Asian food family-style, about $10 per person, a chance for teams to exchange findings, view each others photos, and chat about rarities seen that morning. Count partici-pants are not required to be CAZBA members; read more about this annual tally at cazba.org; to RSVP as a participant or ask questions about the count, email census coordinator Ron Rutowski rrutowski@cox.net
