"Not a great day, cloudy, windy and drizzling at times. The weather report was totally wrong but we figured we will take on Donaldson and Emmons and depending on the time, shoot up Seward. We did not want to get home too late being it is Sunday and we need to get things done prepping for work on Monday. So we headed out a little late (7:30am) we started! Conditions we a bit muddy but we found the calkins brook trail really nice. We made good timing getting up to the cole between Seward and Donaldson, shot to Donaldson by 11am. and Emmons by 12. Views were no good but the sky was clearing, made " - hbotc, Aug 6, 2017
"Solo. Donaldson, Emmons, Seward. All 3 of these summits were terrible, unfortunately. I started out from Corey's Rd (gate is still open, road was dry!) at around 05:45. The first portion of the hike leading to the Calkins Brook herd path was largely uneventful, mud with a thin layer of icy snow on top of it, but bare boots were enough. There was a phenomenal amount of blowdown across this trail though WOW. It all looked relatively new, so I'm guessing this past weekends storm had something to do with it, maybe 20 trees laying across the path? After hitting the bucket cairn I hooked a left and " - kellieirene, Oct 25, 2016
"Journey across Seward - Donaldson - Emmons, with Jay and Nolan. The weather started nice, but began to look ominous at the summit of Emmons. Thankfully we were able to make the trip back over Seward and down the rockiest sections before we lost daylight, and the rain began to fall. The last few miles in solid rain and darkness made the return to the tents. " - Kazmuglin, Sep 19, 2015
"The 2nd mtn of the day. Great views from 2 different spots, one east, the other west. The blackflies on the summit looking east were bad, which was a shame since that was the viewpoint looking at the 46ers. Went on to Emmons, then back to here to leave the Sewards." - newenglandwarrior, Aug 7, 2015
"Enjoyed a nice winter hike to climb Don, Emmons and Seward today. Temps were brisk in the am with a forecast of mid-teens and then a storm coming in late in the day. As it turned out the winds would pick up by mid morning and the storm would be upon us by noon which made for some tough conditions. Headed in via the horse trail to Caulkins Brook HP (roughly 3 miles) then up to Donaldson (~ 6 miles in), over to Emmons( ~7 miles in) back to Don and over to Seward (~ 8.5 miles in) and down to Ward Brook and out (~ 5 miles once at Ward Brook junction). All trails were broken out except Seward w" - deb-and-rob, Feb 21, 2015
