Sitting here typing from the Curly Redwood Lodge in Crescent City, California, during another redwoods visit ... Yesterday morning, I went to Avenue of the Giants (Humboldt Redwoods State Park), and measured a tall maple I found some weeks ago. Apparently, this is the tallest (known) of any Acer species in the USA, and I've heard of none taller anywhere else either. The laser photo shows the first increment. The rest of the the height was the trunk's extension below the laser. Acer macrophyllum > Bigleaf Maple Height > 157.8 ft. / 48.09 m Circumference > 9.5 ft. / 2.89 m Name > "Humboldt Honey" Location > Avenue of the Giants There is a younger guy (Zane) who has been exploring lately, just off to college, whom I suspect will look for more soon. He found a rash of other tall hardwoods the past year, farther south. It's hard to imagine there's not one taller yet in this area. Will be up in Jedediah Smith Redwoods today, doing hiking and photography. Recent rains have washed everything clean. The air feels so fresh.
