1 Humboldt Redwoods State Park
I spent an enjoyable Sunday in early June 2018 looking through the groves along the Avenue of the Giants, including Bolling, Kent, Federation, and Founders Groves. There were a series of tall trees I wanted to locate in each of these groves and was successful, combining older clues involving groves and tree descriptions with newer information available on Open Topography LiDAR portal. Finding the trees became a test of GPS navigation and inference, with a bit of range finder height measurements to confirm certain tall trees.
The Bolling Grove sits right by the Avenue. The area of tall trees is very small, and the trunks are arranged in a pleasant pattern that recalls a sculpture garden. Three of the four trees in the main grouping are over 100 meters. Here you can see the rendered LiDAR point cloud data, where purple is 105 meters in height and red is 100 meters in height.
Then you can compare the LiDAR with the photo of the tree grouping. The one in front is 100 meters, then the ones to back left (Bolling Stovepipe) and back right have crown points above 105 meters.
The grove is dedicated to Colonel Raynal C. Bolling who was killed in action 100 years ago (March 2018) during World War I.
A little later in the day I hiked the Founders Grove trails. There are many great trees all over this grove, with 200 or so trees in the grove over 100 meters in height.
Here is one of the tall trees in Founders Grove, aptly named Javelin. Sure you can see why.
2 Jedediah Smith Redwoods
A few days later in the same week I did some group hikes in Jedediah Smith Redwoods State Park, near Route 199 in the Walker Road area. There are nice flats in this area with a good number of 100 meter plus redwoods. I believe this area has the northernmost 100 meter coast redwood trees.
The loop trails along Walker Road are really nice. The amount of western hemlock is amazing, they grow everywhere on everything.
Here are a couple tall trees in the area, both well above 100 meters. The bench was built in 1972 as a viewing point to the second tree pictured. Its trail is no longer maintained but still gets a lot of use.
I will post more about this trip later. Thanks for reading.
