Trees planted today are not for us but for future generations. Mariposa Grove is the largest of three Giant Sequoias groves located within Yosemite National Park and it contains approximately 500 mature giant sequoias (Sequoiadendron giganteum) which are all over 1000 years old. These magnificent trees are why most of the visitors and hikers love to come here to explore this beautiful grove. These areas are also being protected for the benefit of future generations since 1864 after President Lincoln signed the protection legislation. I am so glad to have the opportunity to visit Mariposa Grove in late Apr 2015 (we made it just on the cusp of opening as it was closed for a longer period due to a snow storm). The grove is usually closed from November to about mid-April and only accessible during these months via foot or snowshoe. Again, lady luck is on my side as it was closed again for Mariposa Grove restoration project that started in July 2015 and will only re-open in 2017.
