Today dawned with clear blue skies and I was hopeful that my main leaf-viewing day and a drive to the top of Mount Washington<\/em> would reveal great views. Alas, the clouds rolled in to defeat my optimism but I still had a great time on Mount Washington.<\/p>\n The online fall color reports suggested that the leaves along route 2, which follows the northern edge of White Mountains National Forest<\/em>, were just about at peak color and this also happens to be the gateway to the Mt. Washington Auto-Road which climbs to the summit of the tallest peak in the northeastern US. The leaves were, indeed, colorful but, by the time I had reached the higher altitudes of the National Forest where the most impressive displays were likely to be, clouds shrouded the hill tops. By then, of course, I knew I was not going to see fantastic views from Mt. Washington but driving up and down through two cloud layers was fun and I encourage you to watch the ascent or descent in the road video to get an idea of what it was like.<\/p>\n Mt. Washington is also a historic location for both meteorologists and physicists. A weather observatory was established at the summit in 1870 which is still operated today and, in April 1934, a wind speed of 231 mph was recorded there. This is the highest wind speed ever recorded apart from very brief gusts associated with hurricanes or micro cells indicated by Doppler radar to exist inside tornadoes.<\/p>\n During the 1960s the weather observatory and a station at the base of the mountain were used by physicists to conduct a series of experiments that were able to precisely confirm Albert Einstein’s formulae for predicting time dilation and length contraction as hypothesized in his Theory of Special Relativity. I used to have my students collect and analyze data from old film of those experiments, which showed the road, and that gave added meaning to today’s experience.<\/p>\n Unfortunately, clouds enveloped hill tops and limited nature’s colorful display in the White Mountains National Forest.![\"Mt](\"http:\/\/relativerest.com\/blog\/wp-content\/uploads\/2018\/10\/Mt-Washington-Base.jpg\")
\nThis photo of\u00a0 Tip-Top House, built at the summit in 1853 as a hotel, shows how the weather changed as I ascended the 6,288 foot peak.![\"Mt](\"http:\/\/relativerest.com\/blog\/wp-content\/uploads\/2018\/10\/Mt-Washington-Tip-Top.jpg\")
