Looking west towards the mountains were massive thunderclouds, threatening to roll down onto Denver and engulf it.  The clouds were thick and black, and an intermittent rain started up as I began my ascent into the Rockies.  Just past Idaho City, at the beginning of the  uphill climb to Mt Evans I hiked a bit along a beautiful creek, finding Black-capped Chickadee, House Wren, and Cordilleran Flycatcher.

Echo Lake at 10,000'

Mallards at Echo Lake
In the forest surrounding Echo Lake were  Calliope Hummingbird,  Red-naped Sapsucker, White-breasted & Red-Breasted nuthatches, Mountain Chickadees, Ruby-crowned Kinglets, Clarke's Nutcrackers, and both Stellar's and Gray Jays.

Bristlecone Pines
At the tree line were Bristlecone Pines, with their gnarled branches and tiny needles.  The only birds were Dark-eyed Juncos and White-crowned Sparrows.  From here on up was nothing but tundra, with lots of beautiful flowers.  Earlier in the day it had hailed, and patches of it were still in evidence.

Bighorn Sheep
Bighorn sheep came out onto the road looking for handouts, causing traffic to come to a dead stop.  Later that day I also spotted mountain goats, but they stayed high up off the road..

A variety of flowers blanketed the tundra!


Thunderclouds over the front range

At Summit Lake, elevation 12,280', I looked in vain for Brown-capped Rosy Finch.  Although I'd seen them there several years ago, I had no luck this afternoon.  I did see many beautiful flowers and dramatic scenery.  I also got light-headed as I hiked up from the lake--the altitude really started to effect me!

Water Pipit
The most common bird throughout the alpine country was the American/Water Pipit.  Flocks of them would flit about, and I'd always check them out hoping to find they'd be finches.
Numerous yellow-bellied marmots and pikas squeaked and grunted from their rocky lairs; always watchful.

The same one!

Yellow-bellied Marmot
I was lucky that the thunderclouds never dumped on me the whole time I was up on the mountain.  It provided spectacular lightning displays all around, and up on the mountaintop it was very windy and cold.  Good thing it was August!  

Thunderclouds over Denver
On the way back down through Idaho City I stopped to watch a feeder setup at a cabin along the road.  Dozens of Broad-tailed and a single Rufous Hummingbird were enjoying the sugar water as I watched contentedly.
