Had a great time hiking the mountain with my friend Julie. Unfortunately, the summit was in the clouds when we got there. Saw some limited views down to the valley, but many more as we descended.

Found it while climbing all ADK fire towers. Counted 64 wind turbines NW of Plattsburgh, and many more further away north.
Two of the four concrete footings supporting the tower are badly deteriorated.

Found it in the company of Cron and family. As was the case for Cron, this was my first benchmark find, but getting up the tower was a bit of a challenge due to the wind and cold...and lack of solid, safe handrails. I'd been up this tower some 35 years ago with my dad, and remember that at the time there was a forest ranger watching for fires.

My first "benchmark" find ever. I'll have to be honest, when I reached the summit, I looked around for the marker and I was deceived not to find it. Only after some reading of the benchmark description that I understood the benchmark was... the tower! Oh! That's why the GPSr was always pointing there!

I went up to the top and got a picture of the center bolt with a part of my GPSr (quite windy up there!).

This turned out to be a memorable hike. The trail is awesome and we had the opportunity to see some snow today. We took the old trail to the top, but we went down through the new (and longer) trail. I think I prefer the older one (less muddy and much faster).

Summit had a few inches of snow today. Made for some awesome scenery. Made my way to the top of the tower which afforded some nice views. Also did Lyon"s Lair (GC5ED7) took some pictures from the top of the tower. For what its worth there is a new trail up the summit. This new one is much longer but much less agressive (fewer boulders) although it meets the old trail about 3/4 of the way up and still requires some aggressive climbing. I enjoyed the new trail and will take it again next time I hike the mountain.

Hiked up Lyon Mountain today. Tower is still intact, but in poor condition.

Wandered in woods beyond tower looking for higher ground and found a golf ball
