The telescope tree is best viewed from inside of the tree itself, and you will see how it got its name as soon as you walk inside and look straight up. This tree was burnt from one of many fires in the area, which hollowed out the entire tree.
The Telescope Tree is probably one of the best examples in the park of the Sequoia’s amazing resilience to fire. Because the outer later (inside of the fire-resistant bark) is the only layer of the free that is growing, the center of the tree can burn away and the free can continue living and growing for centuries longer (as long as it can still stand up that is).
In fact, Sequoias need fire to survive. The warmth from the fire opens up the Sequoia’s pinecones that have fallen to the ground, along the seeds to fall out and start growing. Small fires also clear out the brush around the area, which makes it easier for the seeds to sprout. But don’t think this means you should start a fire to help the Sequoias grow—they will do fine by themselves relying on natural disasters, some of the trees in this grove have been surviving because of and despite of them for over 2000 years.
