1 Exploring Mt. Spokane, the Jewel of Eastern Washington Alejandra Calzadillas, Hannah Rolli, Lilia Vasyukhnevich, & Shasta Wright

2 Introduction On May 24 th, 2014, our group researched Quartz Mountain at Mt. Spokane State Park and went on a research hiking trip. Our goal was to search for rock outcrops as well as research the vegetation, area wildlife, the history of the park and the available recreation activities around the park.

3 Area History Mt. Spokane State Park began as a small privately owned parcel of land in northeast Spokane County. Before being called Mt. Spokane, the mountain was called Mount Carlton or Mount Baldy (Arksey, 2006). After officially becoming a state park, the mountain was developed into a major recreational area for Eastern Washington, providing great facilities for winter and summer activities. Millennia of erosion and weathering have worn it to its present height and rounded form. The mountain rises 5,883 feet, although it was once higher than its previous level.

4 Location GPS coordinates to the parking lot at Quartz Mountain: 47°.90452, -117° Take the Argonne exit from U.S. I-90 and continue north to Mount Spokane Park Drive, continuing three miles past the park entrance. Turn right and park in the parking lot 0.1 miles in. Map of route to Quartz Mtn. from Spokane Valley

5 Mount Spokane Geology The rocks that compose Mt. Spokane are Cretaceous aged, two-mica (biotite and muscovite), granites. (Weissenborn & Weis 1976) These granites have intruded a Precambrian banded gneiss that is composed of quartz, feldspar, biotite, and muscovite. (Weissenborn &Weis 1976) Mt. Spokane Granite with muscovite flakes

7 Site Geology Site 2 is a granitic outcrop interspersed with plagioclase feldspar and quartz, +/- biotite at the foot of Mt. Spokane Drive This outcrop has prevalent muscovite flakes ranging in size from 1cm to 4 inches wide Figure 3: Granitic Outcrop Figure 4: Plagioclase feldspar with predominant muscovite flakes

8 Site 3 Site three is also a granitic outcrop about ½ mile south of site 2 on Mt. Spokane drive that features granite with muscovite, plagioclase feldspar and quartz, +/- biotite. This granite shows evidence of foliation which indicates metamorphism Garnets found in some of the rocks also indicate metamorphism Figure 5: Foliated Granite Figure 6: Garnet embedded within pegmatite

9 Site 4 Site four is the same granite as the first two outcrops about two miles south of site 3 This outcrop has no foliation but exhibited much more weathering than the first two outcrops Figure 6: No foliation in this granite!!

10 Wildlife Carnivorous animals – Gray wolf, Canadian lynx, wolverine, martin Ungulates – Rocky Mountain elk, White-tailed deer, moose Small mammals – Pika, Pygmy shrew, bats Birds – Northern goshawk, Boreal owl, woodpeckers Butterflies – Common tortoiseshell butterfly (Pacific Biodiversity Institute) Photo of moose at Mt. Spokane, courtesy of Mt. Spokane Ski & Snowboard Park There is a diverse variety of animals that live at Mt. Spokane State Park and the surrounding area, including several species on the Federal Concern or Endangered list.

11 Vegetation On the hike at Quartz Mountain we came across the Round-leaved violet (Viola orbiculata) which features small yellow blooms as well as lupine and ferns. Mt. Spokane has approximately 192 species throughout the park including many different flowers, trees, grasses, and ground bushes.

12 Recreation The website describes numerous hiking and biking trails, and 100 miles of horse trails. Other activities include bird watching, and wildlife viewing In the winter snowshoeing, snowmobiling, skiing, and snowboarding are just a few activities one can take part in.

13 Recreation- Quartz Mountain One excellent way to survey the beauty that surrounds Mt. Spokane is to stay at Quartz Mountain Lookout. This structure was used up until 1994 to watch forest fires (Mount Spokane Gallery website). Over the summer you can rent out the tower and spend the night there to build campfires or watch the stars above the city lights. Quartz Mountain Lookout looks over the northern Idaho Panhandle and Spokane.

14 What We Learned During this project we learned that one of Spokane’s most beautiful landmarks has much information to offer about the Spokane area. Geologically we learned that Mt. Spokane is composed of an igneous granitic intrusion on a Precambrian banded metamorphic gneiss. This intrusion shows us evidence of foliation and garnets in some areas while others have no foliation at all. Mt. Spokane has several recreational activities for people to enjoy, whether it is hiking or biking the numerous trails in the summer to activities in the winter such as snowboarding and skiing. We encourage everyone to enjoy this wonderful landscape and to please remember to be cautious because even though there is a paved road leading up to the summit, it is still the wilderness.
