Were back in civilization again. The roads narrowed significantly with cliffs pressing up close against the highway. The morning was kept interesting with needed to pass through 6 small tunnels. Bikers are asked to press a button upon entry to turn on a blinking light on the road that signified that cars should slow down. Much of this region was beautiful with great views of Mt. Hood and the Wild and Scenic Klickitat River. A hawk even dropped his catch by our feet. Towards the end of the day the roads became more narrow and the cars kept coming fast and close. June was blown off the road by a logging truck but she caught herself with one of the cliffs. The stress level was ramped up with the crossing of the metal Bridge of the Gods into Oregon that lacked a bike lane. We spent the night at the KOA in Cascade Locks. This was a town was named after the series of locks that were installed on the Columbia in 1896 to help shippers and steamboat lines compete against railroads. This bypass around Cascade Rapids, a second large set of rapids on the Columbia River was flooded by the Bonneville Dam. The Bonneville Dam was created primarily for power generation and navigation but fish ladders were installed allow the steelhead and salmon to spawn. These still do not let the bottom feeding white sturgeon to migrate upstream but since this is the most downstream dam on the Columbia River, their population is strong here. The Bonneville Dam has a Visitor Center that showcases their work on fishery management. There are 23 types of sturgeon, 7 found in North America and only 2 are on the Pacific Coast. Sturgeon are prehistoric beasts that have changed little over the last 200 million years with body armor and a skeleton that is more cartilage than bone. The Visitor Center includes ponds with underwater viewing areas, including one that shows off its 25 year old white sturgeon. This fish is relatively small, with some known to reach 20′ and weigh as much as 1800 lbs. Sturgeon under 42″ or over 60″ have to be released.
