Tower Mountain - 13,552 and Dome Mountain - 13,370


RT Length: 14.13 miles

Elevation Gain: 4500’

I parked at 10,000’, just after the town of Eureka. My truck could have driven up the 4WD road, as it was a nicely graded, wide road, but I didn’t know it at the time and figures starting at 10,000’ sounded pretty good.


We were once again experiencing summer storms, so I was up and on the trail at 4am. I followed the road as it rounded the mountainside, heading west.


Suddenly, I saw a fox, about 10 feet in front of me on the trail. I shined my flashlight at him, and said “Hey Fox!” The fox walked up to me, and stood about 2 feet away. He was brown with black feet, and had a piece of grass sticking out from its lips. He looked up at me like a puppy asking for a treat. I wanted nothing more than to pet this cute little guy, but knew his behavior was off for a wild animal. I loudly tapped my trekking pole on a rock and told him to move. He jumped a few feet in the air, then skirted around me. He didn’t leave though, until I did it again.

I continued on in the dark, making great time, until the sun began to rise. That’s when I noticed I was heading the wrong way and realized I’d missed my turn in the dark. I’d gone a mile past my turn, and added 600’ of elevation gain to my day (already taken off my stats). Drat! I turned and ran a mile down the road, to the correct turnoff at 10,500’


I then followed this road, which paralleled the South Fork Animas River


There were a few dispersed campsites along the way. The road ended at a creek crossing. Well, it didn’t end, but you couldn’t drive any further.


I crossed the creek, passed an abandoned mine, and the road curved. This is where the trail began. It’s an unnamed pack trail, and very difficult to follow. Don’t cross the creek.



I passed several large runnels


And noted now that I had a visual my intended decent route was going to need to be modified, as it cliffed out. I resolved to instead take a different ridge down, which looked like it ‘went’ and continued southwest to treeline. Once again, there wasn’t a consistent trail here, but I did come across game trails I utilized when available.


Now at treeline, I needed to access the upper basin. This is how I got there. There were TONS of game trails in the area.


I was headed northwest, aiming for a saddle



Once at the saddle, I turned left to ascend the ridge and follow it south. Initially I hit a scree-filled gully, but it was short.


I then hit some rocky tundra area, but once I ascended this I hit a class 1 trail. This trail took me up and over PT 13060, then it went downhill while I followed the tundra towards Tower Mountain.





Here’s my route up Tower Mountain (which has a tower…)


And a few step by step pictures (this is all class 2)





I summited Tower Mountain at 8:50am


Tower Mountain:

From Tower you can see Dome Mountain to the east, but it’s not a simple ridge walk to get there.


I followed the ridge to the arrow, and then I descended (arrow) to avoid some nasty terrain just before making it to Dome along the ridge.


Here are some pictures of the ridge


Looking back at Tower


This is where the ‘fun’ begins, and doesn’t end until you’re back on the trail you hiked in on... I left the ridge here, at 13100’, and descended into Cataract Basin, making sure to stay high. No trails here, unless you stumble upon a game trail.



I then ascended the saddle between PT 13321 and Dome Mountain. There was a lot of scree here.


This is my general ascent route up Dome Mountain. I just went straight up the face, heading east. Now is a good time to look at your route.


Here are some step by step pictures. Now is a good time to put on your helmet if you haven’t already


This is difficult class 3, easy class 4, and most of it is pick your own route. There were plenty of hand and footholds, but there was a lot of balancing involved, and not a lot of room. Very little margin for error. This is the route I took


That was your warm up. Now to ascend the larger wall. Same rules apply, but with an added degree of difficulty


Woot! Now some tundra to the difficult part


The last 300 feet of climbing is done on very loose rock. Trust nothing. It’s all class 3, but the terrain is rotten. Here are some photos. I continued east, and headed straight along the ridge to the summit.




I summited Dome Mountain at 10:45am


Dome Mountain:

There were a ton of bees and flies at the summit, so I didn’t stay long. I was making this a loop, and wanted to head north into the basin I’d hiked in, towards the South Fork Animas River. I wasn’t 100% sure this would work, but as I looked this morning from below I knew if I could get down the rocky area I’d be good to go. I headed south and followed the ridge. This was also class 3-easy 4, but much more stable and easier to navigate than the ridge I’d taken up. There are rocky chimneys to descend, but mostly tundra. If I were just doing Dome, this is the route I’d take up and down.


Here's looking back on the ridge. It’s a lot longer than it looks


This is also a good view of my ascent route from this morning


Now all I had to do was head down an avalanche runout, back to the trail.


Here’s looking back up that avalanche route


Now back on the trail, I followed it to the 4WD road


And followed the road back to my truck


I made it back to my truck at 1pm, making this a 14.13 mile hike with 4500’ of elevation gain in 9 hours.


As I was putting my things away, I saw the same fox I’d seen that morning, this time sitting on the side of the road, overlooking Eureka below.

Well that closure seems new for this year. Wonder who or why closed it. There are some excellent sites there for camping that don't get used even on a busy weekend. Bummer.

There's now just one before the closure. It's a big one, but it was full with a large party (I saw 4 vehicles parked there on my way out that weren't there on my way in). The other spots are still there, but you'd need to hike in. They're taking 'no motorized access' seriously, but there were tire tracks present in the mud after the closure, so you're right, it must be recent. The mine looks beyond condemned, so maybe that's why they closed the road? The trail after the mine is extremely faint.
