Geology

The origins of these mountains began approximately 40 million years ago during the Eocene age. During this time period, sandstone and siltstone formed in the area. Additionally, igneous rocks and basalt flows combined with basaltic sandstone to create many of the mountainous formations. Other sedimentary rock in the area formed more recently, around 20 million years ago. It is hypothesized that portions of the area were islands during parts of the Eocene era. [4] The entire coast range sits on a convergent tectonic margin interacting with the Juan de Fuca Plate that is subducting beneath North America tectonic plate. [5] The range is part of a broad, plunging structural arch of sedimentary and Tertiary volcanic strata that is being uplifted. [6] Other portions of the mountains consist of marine sedimentary rock. [7] The basalt in the area comes from basalt flows that covered much of Oregon that originated from fissures in the central portion of the state. [6] It was during the middle Miocene period that the range was uplifted in the broad, northeast-plunging arch. [6]

Flora and fauna

Forested parts of the mountain include Sitka spruce, western redcedar, Douglas-fir, and western hemlock. [8] Other plant life native to the mountain are Coptis laciniata, salmonberry, salal, sword fern, Oregon grape, bracken fern, and others. [8] [9] [10] Invertebrates include millipedes, collembolans, spiders, beetles, and various centipedes. [8] [9] Animals that inhabit the area are weasels, chipmunks. black bears, snowshoe hares and deer. [9] Birds include chickadees, kinglets, woodpeckers, jays, brown creepers, and red crossbills. [9]

Location

Rogers Peak is approximately 8 miles (13 km) north of Lees Camp on Oregon Route 6 with access via North Fork Road. [11] Hiking the mountain is about a 3.5 miles (5.6 km) round-trip with an elevation gain of about 1,100 feet (340 m). [11] The mountain, located on private timber land, is near the Oregon Coast. [12] [13]

Name history

In 1964 the mountain officially became Rogers Peak. Previously, it had also been referred to as Blue Lake Peak and Nels Rogers Peak. [2] The mountain was named for Nelson S. Rogers, who was the Oregon State Forester from 1940 to 1949. He was a prominent figure in the rehabilitation of the Tillamook Burn. [14]

Ochoco Mountains

The Ochoco Mountains are a mountain range in central Oregon in the United States, located at the western end of the Blue Mountains. They were formed when Permian, Triassic, and Jurassic rocks were slowly uplifted by volcanic eruptions to form the Clarno Formation. Today, the highest point in the range is Lookout Mountain. The dominant vegetation on the west side of the range is old-growth ponderosa pine; on the east side, western juniper is common. The western area of the mountains is administered by the Ochoco National Forest, while the southeastern section is part of the Malheur National Forest. The Ochoco Mountains are used for hiking, camping, bird watching, rockhounding, and hunting, as well as cross-country skiing in the winter.

Siletzia is a massive formation of early to middle Eocene epoch marine basalts and interbedded sediments in the forearc of the Cascadia subduction zone, on the west coast of North America. It forms the basement rock under western Oregon and Washington and the southern tip of Vancouver Island. It is now fragmented into the Siletz and Crescent terranes.

Geology of Iran

The main points that are discussed in the geology of Iran include the study of the geological and structural units or zones; stratigraphy; magmatism and igneous rocks; ophiolite series and ultramafic rocks; and orogenic events in Iran.

The geology of Georgia is the study of rocks, minerals, water, landforms and geologic history in Georgia. The country is dominated by the Caucasus Mountains at the junction of the Eurasian Plate and the Afro-Arabian Plate, and rock units from the Mesozoic and Cenozoic are particularly prevalent. For much of its geologic history, until the uplift of the Caucasus, Georgia was submerged by marine transgression events. Geologic research for 150 years by Georgian and Russian geologists has shed significant light on the region and since the 1970s has been augmented with the understanding of plate tectonics.
