Hmmmm... Posting at almost midnight, summiting South Sister around sunrise and posting again around 9:30am... Over a dozen miles round trip at a minimum, almost 5000' elevation gain and loss, with no sleep in ones mid-50s. I mean I guess if you are really a Himalayan mountaineer that's just another day, but still...
Yeah...I'm not seeing anything that looks likely to bring record highs anytime soon. In fact it appears we have at least one more cold shot coming early in week two.
What time did you start? To make it up by sunrise, you would have had to have been at the trailhead incredibly early. If you went the Green Lakes route that's probably what, 7-8 miles from the Sparks Lake trailhead to the summit?
