Summit Tunnel, 1999
Western Union Telegram
October, 1867

CPRR Crew:

We're losing time on these tunnels. Lewis Metzler Clement is our engineer. He says we will need 15 tunnels to get us through the Sierra Nevada Mountain Range. You have to find a way to help us bore through this hard granite rock quicker.

This is Summit Tunnel above Donner Lake is 1,659 feet long. Is that about 

1 football field long? 

5 football fields long?

10 football fields long?

(Hint: 3 feet = 1 yard. 100 yards - 1 football field.)
