Detailed Trip Report: First Part
7:45 a.m. We departed from Campus.
We drove north on Highway 101. As we continued north through the Highway, we passed through Yachats, a town that is approximately 75 miles. Just on the left past the Adobe Motel was the turn-off to Smelt Sands Beach which was our first stop. ( that’s all copied)
Stop 1: Smelt Sands Beach.
Smooth and brown rocks are molded together by wet beach sand. The sand is, however, coarse with contents including, quartz, basalt, shell pieces, serpentine and agates. The rock forming the base rock formation is present in the sand signifying the rock is broken down by erosion.
Different rocks are also exposed and are believed to be from the Cenozoic Era. They are featured as part of the Yachats Basalt and are Late Eocene (36-40 million years) in age. These rocks were formed as a result of the cooling of magma from a series of eruptions ( this is all copied from that cheater essay.. not hard to tell see I told you… KEEP This I will alter (Alt and Hyndman 1978).
There is the existence of a Pleistocene terrace where the town of Yachats is built. The terrace was probably formed when the sea level was lower, and its deposit is 10,000 to 1.8 million years old. It cuts into the Yachats basalt sequence (Snavely, 1980). Its present level, which is above, the present sea level, is attributed to either the rise of land due to tectonic activity or dropping of the sea level. It is, however, difficult to know where the uplift of the land is possible in such an active coastline. The Smelt Sands Beach is located to the South of the start of Yaquina formation. A basalt flow is found at this spot. It lies beneath the Pleistocene terrace. This basalt is about 40 million years old. The Pleistocene, on the other hand, is about 1.8 years old. What happened between the formation of the basalt and the Pleistocene is not known yet. However, some researchers speculate that land movement could have occurred which led to dropping of the sea level or rising of the land. The whole town of Yachats has been built on this beach terrace.
Information about the town of Yachats indicates that much is of it occurs in a zone that prone to tsunami if another Cascadia subduction occurs. The part of the town, which is not, in the tsunami zone is found on the hillside. However, this part also risks destruction from the tsunami-causing earthquake. Studies carried out by researchers indicate 50m of beach would retreat in this region should a cascadia subduction occur (Snavely, 1980). This means that the biggest part of the Yachats town would be destroyed considering that most of the premises in the town, which include shops, hotels and residential houses are within a distance of 50m from the water. Plants found in this region include bog anemones and gold-eyed grasses..

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Lab Field Project Point St George
1. POINT ST GEORGE, CA
TOLOWA DEE-NI’ HERITAGE AREA
All pictures taken by me, unless otherwise cited.
2. TOLOWA DEE NI’ HERITAGE SITE
Point St George is an archaeologic heritage site
(designated as such in 2002) in northern California, just a
few miles south of the Oregon border. It is the 3rd most
western spot in the United States. It is also only 12 miles
from my house, so I get the perk of being able to visit
often. (Bosworth)
Just looking at the panoramic views from the point,
coastal bluffs and geological ridges show the rich history
of area.
3. Just a quick walk from the parking
area down through a valley, you
reach the edge of the beach
where you can find tidepools
aplenty during low tide. To the
north is a wide expanse of sandy
beaches and to the south is rocky
ridges full of geological treasures.
4. SEA THRIFT
(Armeria Martima)
Along the path leading up to the
beach there are many different
types of flowers and plants, but I
like the sea thrift the best.
Also called Lady’s Cushion, it is a
coastal perennial that looks like
grassy foliage when not in
bloom. It fares well even with
little water, and stands tall when
hit with salty water. (Jordan
Valley Water, 2017)
5. HERMIT CRAB
Hermit crabs have over 800 species worldwide. Most are
ocean-dwellers, with only one being freshwater.
They are omnivorous scavengers, with wide variety in
their diets, including bits of mussels and clams and
macroalgae. (Sartore, 2020)
They aren’t *real* crabs, as they do not have an
exoskeleton and use found objects (usually shells) as
makeshift homes.
Fossil records of hermit crabs using gastropod shells
date back to the Late Cretacious, and even older fossils
show them using ammonite’s shells as homes. ( Hermit
Crab, 2018)
(Paguroidea)
6. SOLITARY
ANENOME
Scientific name is Anthopleura Sola
(Leslie, 2014)
They are slow-moving carnivores,
using their tentacles to capture prey
and fend off other predators.
Its tentacles are covered with
nematocysts, tiny stinging capsules
that inject poisons into their prey. If
you touch them your fingers many
feel a little tingly or numb.
(Klinkenburg, 2020)
7. PRINCIPLE OF
INCLUSIONS
This wall of rock was very interesting to
come across. The longer I looked at it,
the more I discovered.
I believe it is a good example of the
Principle of Inclusions, as the rocks that
are inclusions must be older than the
material that is surrounding them.
The weather and ocean eroding the
surface of this rock face gives us a good
look at many layers of geologic history.
(Tvelia)
8. Just yards from each other, there are
many examples of unconformities
along the coastline of Point St
George.
Layers of erosion on the top left
picture show us an example of an
angular unconformity.
The top right picture shows a
disconformity, exposed by erosion by
the ocean tides and coastal weather.
(Grippo, 2010)
9. ROCKS AND
TIDEPOOLS
There is no shortage of rocks,
shells, sea animals and other
treasures to explore along just
this little part of the coast.
We had it mostly to ourselves,
save for a few agate-hunters
scouring the shores for agates
washed up in the last tide.
10. COASTAL
AGATES
A popular pastime for northern
Californians (and southern Oregonians for
that matter) is hunting for agates along
beaches. I myself have hunted for them for
years and have quite a collection in jars
around my house.
An agate is a “translucent variety of
microcrystalline quartz”, usually formed in
cavities of igneous rocks, allowing silica to
form opaque spots or bands around the
translucent quartz. (King, 2019)
They come in a wide variety of colors, but
the most common that I have found would
be just clear with white bands or spots.
11. When I found this rock I wasn’t sure what it was. In fact, I am still on the fence! But after some
research I am fairly sure that it is an igneous rock called scoria.
It is similar in composition to basalt rock or pumice. It is formed when magma that is full of gas
flows or is blown from a volcano. The molten rock solidified before the gas has time to escape,
forming bubbles or tube-shaped holes within the rock. (King, 2020)
12. BASALT
This particular rock I believe is basalt,
which is the most common type of
rock on earth.
It caught my eye because of the
pitted erosion pattern on it. This
erosion could have been from water
drops, ocean etching, or gas bubbles
as it was forming from magma.
