Above:  Redwood Mountain Grove area around the Hart and Roosevelt as seen from about two miles down the Sugar Bowl trail on the opposite ridge.  Notice the right hand (south) edge of the pic has very little left with a healthy green color.

The Redwood Mountain grove has been closed for some years now due to the KNP Complex fire, but if you are anything like me, you'll have been wondering about the trees and trails in there since then.  My friend Chris and I have just checked the area out in a couple weekend walks and it appears to be as bad as you could imagine for the southern quarter or so of the grove, the further north you are the better the trees look.  The trailheads and for most of the first couple miles of the trails the trees are in good condition.  Unfortunately, that is not the case for the trees at the latter ends of the trails.  We saw near 100% decimation of the trees on the southern most section of the Sugar Bowl trail and its not very far to the south of the Roosevelt and Hart trees that it is nearly as bad on the opposing ridge.
 
Unfortunately, the groves largest tree, the Roosevelt does not look like it will likely survive this fire's effects either.   The Roosevelt is very much a snag with only one leaf bearing arm left upon it, and a lot of its bark has peeled off showing the trees white bones beneath.  The sole remaining branches' bough of leaves look colorized, like they are drying out, and the leaves may be only a heat damaged remnant showing for a couple years before the moisture within the tree fades away.  We will have to look at it in a season or two more and see what happens.

The Hart tree does look like it will make it, it shows some damage, but its not  fatal looking.  Formerly a quite tall tree, the Hart will be shorter now, but it still sports a half dozen branches up high producing the proper bright colored greenery. 
 
The Sugar Bowl trail and its giant sequoias are in good shape for its first half;  but after the burn demarcation line it becomes a wasteland, and no one will want to see what is beyond that.  The trail however, up to the burn, is no problem to discern, it is clear and easily traversed.
 
The canyon trail is in pretty good shape, likely because it had the greatest concentration of water in it during the fire and trees having more moisture inside them survived better.
 
The Hart/Roosevelt trail is tough to follow in places now that its been in disuse for a while, and becomes impassable in some places due to the undergrowth that is overrunning it now that the tree cover is no longer solid as it used to be.  The typical post fire thorny low brush is taking hold of large areas, especially in the south part of the grove that was badly damaged.  It becomes better to go off trail by the southern reaches of the trail.
 
The park officials told me that they were hoping to open up the two mile road from quail flats to the trailheads late this year, however they will have a bit of work to do on the trails to make it hike friendly by then.  And it might be better to redraw the paths of the southern end of the trails where the two ridge tracks drop down to where they meet in the canyon due to the fire damage.  That part of the hikes is no longer a particularly pleasant vista.

 Here is a recent pic from Chris of the two current largest sequoias in the grove, Hart on the left and Roosevelt on the right:

Below:  some healthy sections of the grove.  There are still many high concentration areas with beautiful trees in the grove;  even if it has sadly lost a lot of viable square footage from its furthest southern reaches.

I did also find a couple trees to measure in the 20k range.
