Today we went down to the Humbolt Redwood Forest and drove down the Avenue of the Giants through several redwood groves. At our first stop we walked a short loop trail to a Triple Tree with three trunks reaching up to the sky. The redwoods are truly giants. The largest tree in this forest was estimated to be 370ft. tall before it was felled by another tree. Next we stopped at Founder's Grove. This time we took a half mile loop walk. We saw Founder's Tree which is 346 ft. tall and 31 ft. in diameter. Next we saw a tree that had been badly damaged by fires through the years but is still alive. We continued our walk through this grove of ancient giants to the spot where the tallest tree in this grove had fallen. The Dyerville Giant which was more than 1500 years old and estimated to be 370 ft. tall, fell when it was struck by another falling tree in 1991. At 370 ft. tall, it was two feet taller than Niagara Falls and comparable to a 30 story building. Along the way we saw several fallen trees. You could see how thick the bark is. That is one of the reasons that the trees live so long. They are also very disease resistant and and have few enemies. After our walk we drove along the south fork of the Eel River to the Visitor Center where we learned about a huge flood that happened in 1964. Towards one end of the Avenue of the Giants is a drive through tree but there was a charge to drive through it and we decided to pass. We drove back to Fortuna for a late lunch and settled in for the afternoon and evening.
