How cool is this great photo of Portland? It shows a clear-cut hill in front of the Lewis & Clark Exposition of 1905. It marked the centennial of the Lewis and Clark Expedition. It ran for four months, attracting 1.6 million people. And, in the following years, the population of Portland exploded from 161,000 to 270,000 by 1910.
