Black Pond Bushwhack to Owls Head
Ivy,
The reason it didn't seem any quicker is because you went North....don't do that.
Black Pond Bushwhack:
From the end of the Black Pond trail at black Pond follow the "deadfall" trail (pictured in adamiata's post) around to the swampy area on the west end of the pond. Skirt around the swampy area then point yourself on a
340 magnetic (compass) heading. This will bring you out on the Lincoln Brook Trail about 5/8 mile further West than going due North to the trail. The 340 heading will add about 100-150 ft of elevation gain but your feet will stay drier and you should encounter less brush. After you've bushwhacked about 3/4 of a mile you'll reach an East/West ridge. From there you should be able to hear the Lincoln Brook in the valley below (.1-.2 mile). The Trail runs East/West just South of the brook. Turn left on the trail and proceed to the Owls Head slide. (where the fun begins)
You shouldn't get lost unless you really try.
If you go too far East you'll run into either the Lincoln or Franconia brook. Too far west and you should still pass by the corner of the Lincoln Brook Trail where it turns North...close enough to hear the Lincoln Brook below you to the right (North-East). Unless it was real cloudy you would also have a view North through the valley between Owls Head and the Franconia Ridge.
Unless you're pretty handy with a map and compass I don't recommend trying to bushwhack back across to Black Pond. If you miss that little pond it could be a long bushwhack to the Kanc.
While the Black Pond bushwhack bypasses the two worst stream crossings, particularly during the wet season the remainder of the Lincoln Brook Trail is still pretty wet...and muddy.
Other Owls Head bushwhacks:
North-West Ridge:
Rumor has it, in the days before the Lincoln Brook Trail the primary route to Owls Head was up over the Franconia Ridge or the Garfield Ridge into the valley North or West of the Owls Head summit and then either South to the slide or up the North-West ridge. The Lincoln Brook Trail now passes over this ridge between the slide and the 13 Falls Tent site. I've been told the ridge bushwhack is fairly easy though considerably longer than other routes to the summit.
East Slope Winter bushwhack:
This is mainly a Winter route I've heard mentioned here at VFTT, but I'm not very familiar with it. I believe the route starts just North of the Hellgate Brook on the Franconia Brook Trail and heads West up the side of Owls Head to the summit.
