Field Trips and Special Activities 
Friday Field Trips 
A. Chimney Rock Archaeological Area - Chimney Rock is a special place known for its archaeology, spectacular scenery and 
flora. This 4,100-acre area, that varies in altitude from 6500 feet to 7600 feet, was studied by Hazel M. Schmoll who began her 
botanical study in 1932. She identified 304 species on this amazing botanical site. Chimney Rock is home to the Aztec milkvetch 
(. Astragalus proximus), a local endemic, and five species of cactus. 
B. Pagosa Endemics & Rarities Habitat Tour - The tour will drive to roadside populations of four Pagosa endemics ( Phlox 
caryophylla, Ipomopsis polyantha, Lesquerella pruinosa and Castilleja lineata ) and observe their ecological habitats. Several other 
rare species will be observed enroute. Flowering of endemics at this time of the year is most unlikely. 
Saturday Evening Activities (Optional) 
Chimney Rock Full Moon Program (6:00-9:00 PM) - The evening program offers an opportunity to watch the moonrise at the 
Great House Pueblo atop the high mesa, near the twin spires of Chimney Rock and Companion Rock. The evening program includes 
a presentation on the people who lived at Chimney Rock between 700 AD and 1125 AD and music by Charles Martinez, a Native 
American flute player. If you plan to attend this program it is suggested that you order a box dinner to eat at the picnic area at the 
Chimney Rock cabin before the program, A blanket or cushion to sit on, a flashlight, and warm clothing are also recommended. 
Pagosa Hot Springs in downtown Pagosa Springs - The Springs Resort offers the visitor a one-of-a-kind experience in a spectacular 
outdoor setting along the San Juan River. Soak and relax in the 17 individual pools of naturally hot therapeutic mineral water after a 
day at the Society's annual meeting. For information visit their website at www.PagosaHotSprings.com. 
Sunday Field Trips 
C. Williams Creek Research Natural Area - This unique area was designated as a Research Natural Area (RNA) in June 1987. It 
is known for its forest of large stands of white fir ( Abies concolor ) which have apparently remained unmodified since settlement. 
This 545 -acre area occupies a glaciated bench between the Williams Creek Valley and the steep cliffs, which form the boundary of 
the Weminuche Wilderness. Nearly 170 species are known to occur on the RNA. 
D. Piedra River Canyon - This glacial meltwater canyon of Dakota sandstone through which the Piedra River flows is a favorite 
botanical haunt for Pagosa locals. Over 100 species inhabit this beautiful gorge including grass fern ( Asplenium septentrionale ), 
slender lipfem (Cheilanthes feei), kings crown ( Rhodiola integrifolia) and bird's-foot violet ( Viola peclatijida). 
E. Using Your Digital Camera for Wildflower Photography, a Workshop Field Trip - Digital cameras present many of the same 
challenges and opportunities for wildflower photographers as film cameras do, but they also afford many new challenges and many 
new solutions to those challenges. Our workshop will range through many subjects: "How can I use the menu items for wildflower 
photography?", "Should I view through the LCD or the viewfinder?", "How do I envision the finished image while taking the pic- 
ture?", "Do I really have to get down on my belly?", "Is it cheating to use Adobe PhotoShop?". Bring your camera and we will go 
outdoors for some actual shooting in the field.
