- The men in Alexander Ross’s party were paddling against the current
on their trip up the Columbia River. If the men were paddling at a rate
of 5 miles per hour and the current is running against them at a rate
of 3 miles per hour, what was their net gain in mileage on a day when
they paddled for 10 hours? Explain your thinking.
If the men were well rested, they could paddle much faster than 5
miles per hour. What significance does this have in determining the
distance possible for each day of the trek? Explain your thinking.
- Rattlesnakes were a problem for the Ross party several times during
their encampments. Knowing that rattlesnakes grow a new rattle with
each year of life, research how many rattles they are born with and
what the average lifespan of a rattlesnake is. Explain your thinking.
- In lesson 3.5, this journey ended at the mouth of the Oakinacken
River. Explain your thinking on each of the following items:
- What was the average distance traveled each day? Consider the total
length of the voyage in days and mileage.
- With a partner, go through the readings and list the layover dates
(days with no travel).
- Considering several layover days and only the days when the group
actually traveled, what was the average distance traveled each day?
- What supplies did the Ross party have when they reached Okanogan?
