Mallard Lake and DeLacy Lakes, Yellowstone National Park - June 30,2017


Dec 23, 2013
In preparation for a hike with my son in the Sierras, I headed out with my daughter and a friend to Yellowstone for four days with the intent on camping at Mallard Lake with day hikes to DeLacy Lakes and other unnamed ponds in the area.

I've been meaning to get to DeLacy Lakes for three years now, but thing have always come up that kept me from reaching it, so this trip was planned specifically to reach the lakes.

The hike in to Mallard Lake, at 3.5 miles, is relatively easy though it is uphill for most of the way. The trail makes its way through old burn for the most part, though the new trees are starting to get some height after 30 years. Once at the lake, we pitched our tents at campsite OB3 on the east side of the lake.


Route to Mallard Lake - roughly 3.7 miles to campsite 0B3


Obligatory trailhead shot


Katie runs into a Bison early on

Typical trail walking to Mallard Lake - I can remember when these trees were knee high

Chipmunk too

The second day we day hiked off-trail (about 4 miles one way) past a few unnamed ponds to DeLacy Lakes. When we arrived at the lakes, we were entertained by an otter who caught two fish and ate them at the end of a downed log in the lake, while we ate our lunches.

Hard to do a hike without a couple of superheroes :)


Pond #1


Little bit of open space along the drainage - who is the ugly guy in the middle of this shot?


More of the open area, with a touch of snow ahead


Pond #2


Pond #3 - this pond was larger/longer than the first two.

On day 3, we hiked to an unnamed pond that is located northeast of Old Faithful. Our route began on the Mallard Creek Trail but soon turned into an off-trail adventure to the pond.

Unnamed pond northeast of Old Faithful - lots of elk prints in the mud along the shore of the pond


Lunch at the pond - rumor has it that that might be @McGimpkins at the end of the log


Balancing act required for making it to this pond - Katie on her way back to camp


Katie at Mallard Lake - apparently didn't get enough of the matchsticks going to and from the pond.


Mosquito Heaven!


Sunset on day 3 at Mallard Lake.

Day four consisted of us hiking back to out vehicle at the Trailhead and heading home.

Envious of your otter siting. So cool to be able to watch them forage in front of you. Thanks for the report!

I can relate @Tim Valentine , It was pretty amazing (lucky) that he was there when we emerged from the trees next to the lake. If we had reached the lake at any other point, we probably wouldn't have noticed it. I saw two otters fifteen years ago when I was canoeing on Yellowstone Lake. They carried on just off the shore as we let the canoe just drift by them. I would be glad to trade one otter sighting for a mountain lion or wolverine sighting. :)
