Painting the Colors of Winter












Over President's Day weekend, John Adams, a Northwest watercolorist, led a 2-day watercolor course at the new Ecology Classroom at the Basecamp. The course introduced art into the classroom for the first time! With the sun streaming in the windows, it was a perfect Saturday morning for painting.

John's demonstration
John demonstrated his favored method of painting where he gracefully representing trees near and far and a looming mountain with few simple strokes. Instead of using cool blues, purples and turquoise to represent our chilly winter landscape, I was surprised to find John's brush dipped in the warm tones of alizarin crimson, cadmium red and yellow.

 Most participants painted a similar scene using John's techniques, but each piece reflected the personal style of each painter. It was a beautiful way to start the long weekend and gave inspiration to each of us to continue learning and painting through the end of winter!

Bald Eagle Surveys- Winter Foraging


Last Sunday, January 27th, the North Cascades Basecamp lead another successful wintering bald eagle survey in the valley. After spotting our first eagle, a 1st year juvenile, within minutes of meeting at the Barn in Winthrop, we took off. This winter, there seems to be fewer eagles in the Winthrop to Mazama area than last year. This is likely due to a small to minimal run of steelhead migrating back to the hatchery this winter, which differs from last January/February.  It also could be the result of a minimal deer mortality, since the deer have easy access to food this year; With hard winter years, there are more deer mortalities and therefore increased food resources for these scavengers. Another theory is that deeper snow in the Winthrop area during the winter pushes the eagles down-valley, looking for more food and foraging opportunities.    Regardless, we took off south to find eagles.

We began to spot bald eagles along the East Country Road near Twisp where the cows are calving, leaving the fields littered with placentas, a nutritious meal for a bald eagle.  There was also an unidentified carcass (most likely a deer) in the field, which also attracted attention from eagles, ravens, and crows. In total, we saw 17 bald eagles at this site. Several were perched in cottonwoods around the field’s perimeter, while others feasted on the carcass. There was a nice array of juveniles at the field. The group got great views of 1st, 2nd, and 3rd year olds, allowing us to see the progression in plumage, beak, and eye color.

As we continued south along East 20 and 153, we saw 7 more eagles perched in trees near the river. We finally pulled over and discovered one of the night roosts the eagles are using this winter. From 4:45PM – 5:10PM we saw 22 birds fly in to the area to spend the night. We saw 12 of these eagles (6 adults and 6 juveniles) fly to into a portion of the night roost right off the road. As they perched, they noisily communicated with each other. We also saw 8 eagles head up a valley about 200 meters further south. These eagles were most likely headed to a different night roost, although we lost sight of them behind a hill, and do not know where exactly they ended up. We are excited to find out in upcoming surveys!

Want to join us next time? We are heading out again on February 10th and 24th,1-5:30pm; cost is $20/person.  Email info@northcascadesbasecamp.com, or call (509)996-2334 for more information.

Family Weekend at the Basecamp!

The basecamp has been host to many this winter. We have seen friends coming up for a weekend of skiing, honey-mooning couples beginning their wedded life, and families making a tradition of winter skiing with their tots.
This past weekend, a lively bunch came to the Methow: six couples including my and Catherine’s, the biology intern, parents! The group from Capitol Hill in Seattle has returned to the Methow for over two decades. The group of 12 or so adults were all those whose families and children grew up with Catherine and myself in our corner of Capitol Hill.

Many of the children from that group are now in school or working around the country, and the group has changed to a jovial group of adults. Catherine and I had the pleasure of spending the weekend with and parents and friends.
After leisurely breakfasts, accompanied with many cups of coffee, some went skiing, other read books and others enjoyed quiet moments to relax and take in the winter landscape. It tickled the group to reminisce about the ski trips at the basecamp 20 years ago
Instead of playing guitar, enjoying conversation, or going to bed early, evenings used to include intense snow-ball fighting, fort making, sledding, and bedtime stories. Up to ten children under age 10 would take the lodge by storm. One parent said it was their chance to let their city-kids be wild for a weekend and tire themselves completely.
This weekend included lots of laughter, love and good food. Here’s to many more winters in the Methow, Seattle families!

Drum Circle Around the Bonfire


The last episode of Thursday’s Soup and Presentation series included something a little different. Kip and Celeste Roberts came to the Basecamp with instruments of all shapes and sizes. 
After a hearty soup dinner, the group of community members, guests, and employees alike circled around a strong bonfire. Kip and Celeste passed drums, triangles, tambourines and even a wash board to all.

Celeste helped us find our communal beat and together we sang, chanted and enjoyed the warmth of the fire against the winter night.

Some people led the group in their favorite songs, other bravely volunteered to lead the rhythm section and direct the group in call and response drumming. It takes some gusto to guide others through the rhythm of your choice or with your voice.


All in all, it was a fun warm event ending with smiles all around.

Wintering Bald Eagle Surveys in the Methow Valley


This winter, naturalists are braving the cold temperatures while joining the North Cascades Basecamp to survey bald eagle distribution and night roosting locations in the mid to upper Methow Valley.  On January 13th,  five intrepid explorers documented 11 eagles between Twisp and Carlton, three of which were spotted as they were flying into their evening roost. One highlight included an up-close view of several perched juveniles eagles, likely feasting on prey near the river below, as their beaks were covered with blood.

Notice the blood on its beak!

As the group is observing and documenting bald eagles and their locations, they are also becoming skilled at aging these slow to mature birds. Observers expected one of the eagles to be a first-year bird (born in 2012) as it’s head was dark brown, beak had very little yellow on it, and its eyes were still dark brown.  At two years of age, bald eagles have more yellow developing on their beak, lighter brown eyes, a lighter golden brown head, some white mottling on their chest, and a fair amount of white on the underside of their wings. At three years, they have further lightened heads, beak, and eyes, as well as a dark brown stripe behind their eyes. A four-year juvenile resembles a mature adult, except for some minimal brown speckling on their head and tail.   Other highlights of the surveys include great views of an adult golden eagle, two red tail hawks, and two rough-legged hawks near Twisp.

Notes on Mountain Alders and an Infectious Tongue Gall


Many of the Mountain Alders (Alnus incana subsp tenuifolia) in the Mazama area appear to be infected with the fungal disease Alder Tongue Gall (Taphrina alni).

Mountain alders are a dominant, deciduous tree species in riparian zones in Washington and Oregon that often forms thickets (Filip). It is a small to medium sized tree, usually growing to around 50 to 65 feet with a maximum lifespan of 60 to 100 years. A. incana has smooth gray bark, matt green ovoid leaves, and catkins reaching 5 -10 cm in length (male) or 1.5 cm long (female). Its tiny seeds are borne in egg-shaped cones, 2-3 cm long and 1-2 cm in diameter (Flora of North America).

Mountain alders are important trees in their riparian ecosystems. During the summer, A. incana provides critical shade to wildlife and the rivers they grow near, keeping the water at a cooler temperature vital for fish (Fillip). In addition, alders are pioneer species, meaning they are one of the first plants to colonize a disrupted or damaged ecosystem. To do so, alders have adaptations that allow them to grow even when conditions are not ideal. One such adaptation is their symbiosis with nitrogen-fixing bacteria that absorb nitrogen from the air and make it available for use by the trees (Tree Species Compendium). The alders' early presence in an ecosystem increases the amount of available nitrogen in the soil, making it possible for more vegetative species to follow (Featherstone).

The Native Americans also recognized the importance of the Mountain Alder and used it medicinally to treat anemia, internal bleeding, urinary problems, sprains, bruises, backaches, itches, dysentery, and hemorrhoids. They also used it as an emetic, a compress or wash for sore eyes, to cure saddle gall in horses, and when mixed with powdered bumblebees, to ease painful labors (Flora of North America).





When you take a peek around the valley this winter, many of the flowering parts of these alders look a bit strange. Clumps of curly, tangled, ribbon-like structures project from many of the cones- signs of the alder tongue gall.

the bridge at Basecamp.



The fungus Taphrina alni, originating from the geographical area of Austria and Slovakia, is one of the almost 100 species in the ascomycete genus Taphrina, which is characterized by its parasitic mycelial state on a number of vascular plants. One of the ways in which the species are differentiated includes their host plants (Rodrigues). T. alni specifically infects Alders, producing ‘tongue-like’ growths originating either from the bracteoles, in which case the growth points down, or the catkin ovarian tissue, in which case it points upwards. When the catkin is still green, T. alni develops as a flat projection and grows outward between the scales (Bacigalova). Throughout the season, the colors of the gall change with the trees, and remain hard and brown on the catkin until the tree drops them. T. alni spores are produced on the infected cones and are transferred via wind to other trees. While it has been stated that T. alni causes no measureable damage to Alders, the gall is persistent and seems quite widespread in the valley, warranting further research and observation before we can be sure (Wikipedia Contributors).

It will be interesting to keep watch on the Mountain Alders in the valley to see whether animals are less likely to eat seeds from affected cones, if the presence of the gall increases over the coming years, or if the gall causes any other changes to these trees that are so important to our ecosystem.

Winter Wildlife Tracking


On Saturday morning, a determined group of eight gathered near the cozy fire in the North Cascades Basecamp Lodge. We listened as our animal tracking guide, Gabe Spence, described his experience learning about tracks, following animals footprints in all environments, and how we would do just that here in the Methow.

first track sighting

As we embarked into the snowy landscape in Mazama, the conditions proved perfect for tracking. The sun was shining, the snow was soft, the temperature cold enough (as in 3 degrees...brrr!) to have preserved every movement of the animals over the last 3 days.
Gabe identifying tracks

With Gabe’s help, the group quickly spotted tracks with two large imprints in front and two smaller and offset imprints behind. The medium sized animal must hop given the distance between the tracks, and since frogs are out of the season, we decided on the snowshoe hare.

These quick and industrious hares seem to do well in this environment  as we saw their tracks on many occasions.  The  low hanging trees provide fir needles, buds and twig snacks for their seasonal diet. Deer, whose tracks we also found close by in the forest, also devour similar woody treats during the winter season. 

Not only were we able to identify animal tracks, but many of the prints in the snow told the story behind the animal’s movement. Our investigations found motivation behind an animal’s directional movements and the speed of their gait. As one member of the group said, “we are like detectives, using clues to tell us what happened!”

Before returning for lunch, we followed tracks we initially believed to be one coyote. Our group carefully walked alongside the prints and eventually recognized that three coyotes were tracking lunch of their own 

The coyotes’ footprints led us to a tree where we found another animal’s tracks and remains of their lunch: pine cone remnants. Clearly, the coyotes were hoping to feast on unsuspecting red squirrels. The coyotes’ movements through the trees harboring squirrels explained their thinking and know-how to find their prey. 

After warming our cold toes by the fire and a hearty lunch at the Basecamp, we drove to another site in Mazama where Gabe frequently spots cougars. Though we did not find cougar evidence on this day, we found many tracks that would likely be a cougar feast. Deer, weasel, field mice, and coyote tracks lay preserved for examination. 
Small tracks hurried for
shelter in the snow

We finished our tracking day by following a deer. Deer tracks are usually clearly identifiable but can be tricky depending on the snow conditions. Their long, thin legs and heavy bodies leave connected strides forming a squared off trough in the deep snow where many deer have walked.  

In the deep now, deer, much like snow shoers, will generally follow one another, staying in the tracks already laid by another thus saving time and energy.  In the deep powder snow, it was difficult to determine the direction of travel since last week’s snow most often fell into the tracks, obscuring the actual footprint.  After much discussion, we learned from Gabe that in these conditions, the leading pointed edge of the hoof where the track is deeper indicates the direction the deer traveled.

The group after a fun day following tracks!
It was with trepidation that many members of the group took off gloves to put their hand into the snow of the deep track. They found out which direction the deer was walking, exposing their fingers to the frigid temperatures. We continued following the tracks which eventually led us to our parked cars. The deer must have known we were all chilly after an exciting day in the great outdoors.
