Make a master timeline for the geology of Oregon. You will utilize events and dates and pair them with the Geologic Timescale to create a timeline of geological 
events for Oregon. You will need to submit 
some kind of document (.pdf or .jpeg or .docx file) that presents this timeline. 
It can be drafted in many different ways. For example, you could 
draft the timeline in, say, Adobe Illustrator. OR, you could draw the timeline by 
hand and then carefully scan it or take a picture of it and submit the photo. 
On this document, you should include:
-a general geologic timescale, showing the periods (e.g. Triassic, Jurassic, etc.) and 
the epochs of the Tertiary period (e.g. Paleocene, Eocene, Oligocene, etc.), as well as 
dates in millions of years when the transitions are (e.g. Oligocene/Miocene 
transition was at 23 Ma). 
-Next to this timescale, indicate when, and the duration of, major events that  
have discussed. Be as specific or general as you need to be, but the listed 
events noted should include at least:
Deposition of rocks from the Blue Mountains
Deposition of rocks of the Oregon Klamath Mountains
Accretion of the Blue and Klamath mountain Terranes
Deposition of the Cretaceous sediments
Eruption/deposition/emplacement of Clarno rocks.
Eruption/deposition/emplacement of John Day rocks.
Eruption/deposition/emplacement of Western Cascades rocks.
Eruption of the Siletzia basalts
Accretion of the Siletzia Terrane.
Deposition of Coast Range sediments
Eruption of post-Siletzia Coast Range lavas
Eruption of the Columbia River Basalts
Eruption of High Lava Plains rocks
Extensional faulting of the Basin and Range in Oregon
Eruption of High Cascade rocks.
Last Ice Age and glacial maximum
Missoula Floods
Your timeline should be a graphic, not simply be a LIST. 
You do not need to explain or describe the events on this document, but just show 
WHEN and FOR HOW LONG they occurred.
