I have a favorite tree. It is a Scarlet Oak (Quercus coccinea). The scarlet designation comes from its bright fall red foliage that will be apparent when we get to October.

This is a photo diary on some unconventional looking trees I’ve observed in my various local wanderings. Some appear to be growing and prospering under rather difficult and stark conditions. Their shapes are often graceful and even artsy. Others are contorted, gross, gangly, and even eerie, but all are interesting.
Chuckanut Mountain, Whatcom County WA
In stark contrast to the mountainous Pacific Northwest of today, during the Eocene epoch (~ 55 ~ 34 Million YearsAgo (MYA) it was quite flat. However just as today, the region then was lush with vegetation and interlaced with braided streams meandering from what is now Eastern Washington on to the Pacific Ocean. This was a tropical swamp with exotic plants and animals (although some would be familiar yet today). As the streams approached the ocean, they slowed and their sediments of sand, clay, and silt carried from huge rock formations to the east, settled out. Over millions of years these sediments accumulated, were compressed by gravity and tectonic forces, and solidified into immense geologic rock formations. This bucket is about one of these structures – the Chuckanut Formation made up primarily of sandstone, siltstone, conglomerate, and shale, with pockets of coal from the ancient compressed vegetation.
This formation is not only in my backyard it is under it as well. These deposits extend to depths of nearly 20,000 feet in places. My focus here is on the Chuckanut Mountains which comprise 10 separate but related mountains (and hills) in and around Whatcom and Skagit Counties in northwest WA. In particular, I will focus mainly on Chuckanut Mountain itself (for which the formation was named) and a bit on Sehome Hill which is most directly in my back yard. In addition segments of this and related sedimentary formations are spread across the northwest, including the San Juan Islands and up into British Columbia.
What’s a Chuckanut? Although most agree that the name is derived from one of the local native languages, there are several interpretations for what “Chuckanut”, means. I will go with the one from the US Geological Survey: “Long beach far from a narrow entrance.” Beyond that I do not know where the narrow entrance is.
Consisting of sedimentary deposits, these mountains would be expected to show numerous layers of the ages, accumulated over millions of years. And of course they do. Many of these layers now are tilted and folded indicating that they were subjected to tectonic and various geologic forces emanating from several faults in the area. This formation is thought to have been folded about 40 mya, toward the end of the eocene epoch. So now these sedimentary remnants are hills and mountains, nestled as foothills of the Cascade range as well as being dispersed throughout local islands in the Salish Sea.

The sculpting process and creation of honeycombs called “Tafoni”
Tafoni are ellipsoidal, pan- to bowl-shaped, natural rock cavities. These cavernous weathering features include tiny pits, softball-sized cavities, truck-sized caves, and nested and cellular honeycomb forms. Tafoni typically develop on inclined or vertical surfaces and occur in groups.

Cheri challenged us with curves today so I will pull out a recent photo of Gray Whale beginning his dive to feed on the ocean floor. His tail is curvy, his trajectory to the bottom is curvy and the shrimp that he will eat when he gets there are also curvy.
Michelle’s Daily Post Photo challenge has us posting a photo that we took on the way to something else. Good idea. I visited Mt. Baker in WA State last week with some friends from Iowa. As we sadly viewed the melting glaciers on the mountain, we stumbled across a beautiful Spring flower that I don’t see often – An avalanche Lily.
Cee’s fun foto challenge of pink is a great one for flowers. Here is a pink tulip in the rain from the Roozengaarde tulip fields in Skagit County Wa.
In response to Krista’s The Daily Post’s weekly photo challenge: “Intricate.” My entry is a Tree Peony that is just in bloom with all it glory.
