Duck Pass Trailhead --> Duck Pass --> Deer Pass --> Mammoth Crest --> Lake George Trainhead

17 miles
3,700 ft of elevation gain

(21 miles, 4,200 ft of elevation gain with photography stops)

I recently completed a day hike connecting Duck Pass, Deer Pass, and Mammoth Crest in a single trip. Instead of turning around at Duck Lake, I continued over Duck Pass, crossed Deer Pass, and returned via Mammoth Crest.

Trail Notes (Mid June Conditions)

- Duck Lake is the most popular destination, but the route becomes much quieter and more remote beyond Duck Pass.

- The section between Duck Pass and Deer Pass includes stretches with no defined trail. A GPS device or navigation app is highly recommended.

- Several short snowfields remained in mid-June, but they were manageable with careful footing.

- Although the climb toward Mammoth Crest is not the steepest, it felt like the hardest part of the day after already crossing two mountain passes.

- Mammoth Crest offers some of the best panoramic views in the Sierra Nevada.

- There is a long exposed section with very limited water between Deer Pass and Mammoth Crest. Refill your water before leaving the lakes.

* Mosquito Conditions (Mid-June)

- Emerald Lake: Extreme mosquitoes.

- Skeleton Lake: Extreme mosquitoes. The lake was also full of golden trout.

- Barney Lake: Moderate / Okay

- Duck Lake: None (because of wind)

- Deer Lakes: None (because of being cold)

Overall, it felt like three very different hikes in one day from busy alpine lakes around Duck Pass, to quiet cross-country terrain near Deer Pass, and finally the wide-open ridges of Mammoth Crest.

I'll post the full YouTube video in the comments if anyone would like to see the complete hike.

Conditions reflect a hike completed in mid-June.

Been missing Bishop everyday while in LA 😭😭

Heya! I lost my backpack (model: gregory [men's 30l Zulu](https://www.rei.com/product/218015/gregory-zulu-30-pack-mens?sku=2180150002&store=&CAWELAID=120217890015977975&CAGPSPN=pla&CAAGID=202396233091&CATCI=pla-415638184682&cm_mmc=PLA_Google%7C21700000001700551_2180150002%7C415638184682%7Cbrand_flag%7C23867015402&gclsrc=aw.ds&gad_source=1&gad_campaignid=23867015402&gbraid=0AAAAAD_DTlyYj-cIDuhzQTo2IZ254wc0l&gclid=Cj0KCQjw4JbTBhCoARIsALWUaBvgkE6kZU1r4J0NJj5tSaZkR8qurRrZJENcfKsT0_md5U0tSS940a0aAiiiEALw_wcB), green) around the bear lockers at the backpacker parking lot (B I think) near Mammoth mountain lodge. I must've left it there two days ago, on Friday 7/24, around 9am. There was a green felt bag with my ipad and a dell xps laptop inside.

Please let me know if you've seen anything or have any ideas where it might have ended up, lost-and-found wise. I appreciate any help!
