It is no secret that the Siskiyous are my favorite place in the Klamath Mountains. I have spent many days and hiked numerous miles across this region. The Bigfoot Trail travels the entire crest of the range as well.
In early August 2017, lightning ignited a series of fires first named Oak, Cedar, Clear, and Prescott. These fires later grew together and were combined into the Eclipse Complex. Over the next month, approximately 100,000 acres burned in and around the Siskiyou Wilderness. Between last October and now I have had reason to visit much of this area for work and play. What follows are some of the pictures I have taken.
Coastal lowland forests of the Klamath Mountains. From the future book, The Klamath Mountains: A Natural History.
The coastal lowland forests receive the most annual rainfall of anywhere else in the Klamath Mountains. From the north in Oregon the Coquille, Rogue, and Illinois rivers drain southwest Oregon and the Smith River country is California’s only temperate rainforest. The rich soils, temperate year-round growing season, and high rainfall (often over 100 inches) nurture these impressive forests.
Klamath coastal lowland forests are typified by dense, closed canopies on well-developed soils (sometimes serpentines). The dominant tree species have high colonizing abilities, long life, and a wide ecological tolerances to environmental conditions, including dry summers with occasional persistent fog. These forest thrive below the snow belt on the extreme western slopes of the Siskiyou Mountains. Species like Douglas-fir (Pseudotsuga menziesii) and Port Orford-cedar (Chamaecyparis lawsoniana) secure the highest place in the canopy, often approaching 300’. A second canopy forms one hundred feet below and includes species like tanoak (Notholithocarpus densiflorus) and madrone (Arbutus menziesii) where they share an understory with coastal specialists like salal (Gaultheria shallon) and evergreen huckleberry (Vaccinium ovatum). With the high volumes of rain that falls each winter, banks of coastal rivers and streams are frequently disturbed and then repeatedly pioneered by red alder (Alnus rubra).
Botanizing the South Fork National Recreation Trail – Trinity County
Hiking Hell Gate
Hell Gate highlights the lowland interior forest of the southern Klamath Mountains along the Trinity River on the Shasta-Trinity National Forest. The Trinity is surely one of the most spectacular rivers in the state and this hike is along a roadless stretch in the upper reaches of the south fork. The old-growth Douglas-fir/mixed evergreen forest is top-notch, especially along the north-facing sections of trail. Oak woodlands are on benches above the river, with Oregon white oak mixing with picturesque grasslands–though the lack of fire is allowing extensive conifer encroachment. Some of the largest Pacific yew I have ever seen can be found along the trail as well.
The area is dotted with private in-holdings and these beautiful old homes appear at random intervals along the trail. The trail is open to biking and—for these home-owners—OHVs. Swimming opportunities abound and solitude can be easily found, especially in the winter (there are bridges on all major stream crossings). The hike, as written and drawn in Conifer Country, is 7 miles to Smokey Creek but the National Recreation Trail extends the length of this roadless stretch of river—for a total of 15 miles from Hells Gate to Wild Mad Road. The upper reaches of this trail is part of the Bigfoot Trail.
I am highlighting three species below that I found on our hike. One that is a regional endemic, one that reaches it coastal range extension here, and a third that is found across the northern hemisphere. These selections highlight the regional diversity with a biogeographical perspective.
Recently, it was announced that the California Department of Fish and Wildlife caught folks poaching Dudleya farinosa from coastal Mendocino and Humboldt counties. The tip came in from a Postmaster who noticed dirt spilling from a box being shipped to China. Conversations started, one post office talked to another, and they realized poachers were moving from post office to post office shipping boxes of the charismatic Dudleya farinosa. One of the postal workers then reported the suspicious activity on CalTip and this is now an active international poaching case.
This neatly wrapped Dudleya was confiscated by Game Wardens before it left Humboldt County on its way to Asia’s thriving succulent market. Fifty volunteers soon replanted them on the steep hillside cliffs they call home.
In 2012 I first visited the marine terraces of coastal Mendocino County and was captivated by what I learned. The blog and graphic I cooked up after that visit has been one of the more popular entries on this website. In fact, the United States Geological Survey recently published a document on the Marine Terraces of California that features:
How marine terraces form
Soils sequences of California’s terraces
