& the Corps of Discovery

1803 STATES

Label the following 17 states on your map:Use internet map if not sure of these:

America during Thomas Jefferson’s Presidency

Begin Your Mapping Here

Before there were states, the lands being settled were called “Territories”.

Using the previous slide – find these places:

MISSISSIPPI TERRITORY LOUISIANA TERRITORY 1803 (this is what the new LA Purchase is called)

Label these two locations on your map.

Early Cities in the Territories

Look for these 2 places by skipping ahead 4 slides and using the map pictured.

• St. Louis • New Orleans

Place a dot in its approximate location. Label the city name.

TERRITORIES AMERICADOESN’T OWN

SPANISH TERRITORY In 1803 the USA doesn’t own the southwest. Color & Label Spain

Also, shade FLORIDA the same color – US doesn’t own it either.

River Systems

The Mississippi River is actually the dark black “LA Purchase Boundary Line.” Take your BLUE pencil and trace beside the dark line so you can see it’s a river too.

Find St. Louis on your map and you will see that the Missouri River flows into the Mississippi River here.

Trace the Missouri River BLUE north and west until it divides into 3 forks.

Label somewhere along its path: MISSOURI RIVER

Rocky Mountains See next slide for a view

The Rocky Mountains form the WESTERN edge of the LA Purchase. See the Next slide.

By looking at the next slide/map: Draw little ^^^^^ symbols using BROWN.

Start at the top of the map and follow along the western edge of your boundary line.

Make sure you draw mountains on the LEFT side

of the LA Purchase boundary line.

The Corps of Discovery Route

Lewis and Clark led the expedition following the Missouri River. Thomas Jefferson hoped one could reach the Pacific Ocean following a river the whole time. You will discover if this is true.

Now do this Mapping: Start at St. Louis. Using BROWN, make little dashes beside the

river until you get to where the river has 3 FORKS.

Lewis and Clark did not have any maps to help pick the fork to take. Look at the next slides to see what they saw.

WHICH FORK TO TAKE???

Which of the 3 Forks would you choose? They were instructed to follow the Missouri River

to the Rocky Mts.

Pick one of the forks to follow. Make browndashes until there isn’t any more river to follow.

They now would have to cross a Continental Divide

THE CONTINENTAL DIVIDEdivides where the river systems

flow East or West

On The Continental Divide: Looking West

OVER THE MOUNTAINS

Sa-ca-ga-weh-a’s long lost brother gave the Expedition horses so they could carry their gear over the mountains.

Lewis and Clark were told to expect a short trip to the next river… The Columbia.

Well, the trip took a month and it snowed.They ran out of food & had to eat horses.

No River Nearby

When the expedition didn’t have any river to follow they had to do a “Portage”.

This means that while traveling by water you have to get out and carry your stuff until you find more water to travel on.

Their Portage would connect from the Missouri River to the Columbia River.

ON MY MAP

Mapping the “Portage” To do this: Make GREEN dots from where the Missouri

River ended until they reach the nearest river called the COLUMBIA River.

(Hint: Columbia R. is the line on the map not colored & flows into Pacific)

Trace this river BLUE. Label it Columbia.

THE TRIP TO THE PACIFIC

Track the route to the Pacific by making little Brown dashes along the Columbia River and connect to the Pacific Ocean.

It took you only a few minutes to complete this whole route.

It took them a year and a half to travel!!!

Following the Columbia River

Columbia River Reaches Pacific

Winter 1806

The expedition spent the winter at Ft. Clatsop. The next spring they would head back to the USA and report their findings.

Not Done With Museum???

You may now continue to work on it.

Reminder, it is due Thursday.
