Water Cascading Through Beverly Creek

The water cascading down the narrow valley, crashing and tumbling over boulders. Mist hung in the cool air, and the musty smell of fallen leaves and wet conifers filled my nostrils. Beverly Creek, a tributary of the North Fork Teanaway River originates high in the Central Cascades at the edge of Alpine Lakes Wilderness Area. Light snow covered the high ridges, and recent rain made the forest wet, giving much to fill this little creek. The sounds and smells wrapped around me and I settled to contemplate this watercourse.

Scientists recently released “Climate Science: Special Report,” which concluded, “… based on extensive evidence, that it is extremely likely that human activities, especially emissions of greenhouse gases, are the dominate cause of the observed warming since the mid-20th century. For the warming over the last century, there is no convincing alternative explanation supported by the extent of the observational evidence.” In late fall, as I sat beside the creek, it was actually cold – low forties – and I wondered how long I could sit before I needed to move to stay warm.

Thomas Bancroft)Winter snowpack is an essential component of keeping these forests healthy as well as downstream areas. The Teanaway River flows into the Yakima River, and this system is already experiencing water shortages during the summer because of the reduced snows this region has experienced over the last few decades. Allocating water between people, agriculture, and nature is difficult when the amount isn’t sufficient. And this challenge is likely to worsen.

The report also concluded:

Annual trends toward earlier spring melt and reduced snowpack are already affecting water resources in the western United States and these trends are expected to continue. Under higher scenarios, and assuming no change to current water resources management, chronic, long-duration hydrological drought is increasingly possible before the end of this century.”

The state recently protected more than 50,000 acres lower in the Teanaway watershed from additional development because of concerns about water supply. The national forest where I sat, as well as the wilderness upstream, protects additional lands critical to maintaining natural water regimes. Fortunately, Washington State is a leader in combating climate change. During the 2018 Legislative session, our representatives will have the chance to pass legislation that could make Washington a model for how to implementing programs to reduce the release of gases causing climate change while also maintaining a healthy and robust economy.

The double note chip of a Pacific wren caught my attention, and I turned to watch the bird move through a tangle of cedar branches before flying back into the woods. I then rose to walk along the edge of the creek, studying the design of the fallen leaves in the water eddies, some still holding a little yellow color. The water felt cold, not much above freezing. Snowmelt from higher elevations was driving the flow. The crystal clear water should make ideal habitat for aquatic insects. Small fish and American dippers should be along this rivulet. The sounds radiating from the creek filled my heart with hope and resolve. Washington can lead us forward to a solvable solution to this dilemma.

Wood Thrushes Sparing at First Light

The eastern deciduous forest in Western Pennsylvania is full of bird songs in the spring.

The morning fog filled the landscape with a sweet damp smell and dawn had only just started. It was late May in Western Pennsylvania. The eastern deciduous forest surrounded me. A few hemlocks grew on some north-facing slopes, but mostly oaks, cherries and maples dominated the landscape. The gurgling sounds of the stream filled the atmosphere and contributed to the sublime feeling.

I had just rounded a corner when I heard the first morning notes of a Wood Thrush. The flute-like whistle resonated through the forest and immediately a second and then a third began to sing. I stopped my walk to listen and imagined this cinnamon bird with a streaked breast sitting a dozen feet up in a tree proclaiming its territory. Since moving to Seattle, I’ve missed hearing this bird in spring and summer. When I lived in Maryland, I looked forward to its return in late May. One would sing from the oaks just up the street from my house, and I’d listen from my backyard.


We often call migratory birds like the Wood Thrush that breed in the United States “our birds,” but is that the right characterization when they spend most of the year farther south. Wood Thrushes winter from southern Mexico south through Panama, spending at least as much time there as they do on the breeding grounds.

In 2009, I was invited to do a Christmas Bird Count in Costa Rica and arrived late at night before the count day. The next morning, we met at 4 AM to begin our search. The first bird we detected was the “pit-pit” call of a Wood Thrush. Later when talking with folks, I thanked them for sharing “their bird” with us in the United States and told them about the thrill I had each spring on hearing them sing.

Although populations of Wood Thrushes are still strong across the northeast, their numbers have decreased by more than 60% since 1966. They are now listed as a species of “Continental Concern” in the 2016 State of North American Birds’ Watch List.

Other birds, including chickadees, titmouse, cardinals, and Carolina wrens began to join the wood thrushes in morning melody. I closed my eyes to take in the beautiful sounds before continuing my walk.

Rain on the Roof



The rain started last night, and it was supposed to turn to snow. The pitter-patter on the roof was soft and enchanting so I turned off the music. The open window allowed the full sound of the rain to come into the room. The soft melody made the perfect atmosphere to read.
