Intro
The previous weekend, Nate and I had climbed Royal Flush (5.11c, 10p) on Chasm View Wall (a wall of sunny granite just right of the Diamond in Chasm Lake Cirque). We enjoyed the area and the rock so much we decided to return the following weekend. We spent the weekend in Chasm Lake Cirque, under the towering granite walls of the Diamond. It is a rather spectacular place to hang out—one of my favorite bivy locations in RMNP.
Initially, the weekend forecast was for "90% rain", but at the last minute NOAA decided that they really didn't know(a) and that "20%" was a more reasonable prediction. Obviously, work to be done with weather models! But Nate and I had already decided we were going no matter what to keep the weekend alpine streak going, so in the end the bad weather forecast but actually good weather ended up being in our favor by keeping crowds away and allowing us some pleasant weather to actually climb in.
On Saturday we climbed Indirectissima (5.9, 4-6p) on Chasm View Wall. On Sunday we did a long day link-up of Stettner's Ledges (5.8, 6p) on Lower East Face of Longs Peak with Zumie's Thumb (5.9, 7p) on Upper East Face of Longs Peak.
Stettner's Ledges is a famous route that follows the long system of right-facing dihedrals that defines the boundary between Stettner's Buttress and the Diagonal Wall. It was a visionary climb at the time of its first ascent. For awhile it was one of the more popular climbs on Longs Peak, but today has fallen a bit into obscurity. We thought this route had lots of good 5.8ish climbing with a great position.
Zumie's Thumb climbs a narrow pinnacle atop a 600-foot buttress that towers above the south end of Broadway Ledge on Longs Peak. According to the guidebook description, the climbing on the buttress itself (until the final crux 5.9 pitch) does not exceed 5.6, but we felt that we repeatedly got into 5.8ish DFU terrain despite the fact we kept to the route. Getting back to walk-off terrain from the Thumb is a bit complicated. The guidebook mentions rappelling back down to the top of Lambs Slide, but this looked very unappealing, so we climbed a 5.10(ish) DFU pitch on the opposite cliffs to get to walk-off terrain. I enjoyed this route for the adventure, position, amazing summit, and the problem-solving of how to safely get off, but Nate decided it was not worth the risk of the looser rock and descent shenanigans this route has to offer. To those who like a bit of adventure, heads-up terrain, and a day with lots of climbing, I recommend the Stettner's Ledges with Zumie's Thumb link-up. A nice addition for an even longer day and another summit would be to tack on the summit of Longs Peak— this would involve negotiating the Notch by either a rappel or via Gorrell's Traverse (5.4), and then head to the summit via The Stepladder (5.5).
The following page provides a trip report for the link-up of Stettner's Ledges with Zumie's Thumb as well as photos from our overnight in the Chasm Lake Cirque. Enjoy!

Approach
2nd-3rd
Starting from Longs Peak Trailhead, hike to Chasm Lake Cirque. Kick steps up the Mills Glacier right of Lambs Slide (how far right depends on how icy it is and where you can avoid the most ice) then scramble up broken rock to the highest ledge beneath some right-facing corners. It was rather icy for us, so we chose the shortest and lowest-angle route though the snow to the left end of the rock alongside Lambs Slide and from there scrambled mostly 3rd class rock (after an initial DFU 5.0 rock step getting up onto the rock buttress off Mills Glacier) to the base of the route.
Pitch 1
5.6, 150'
Climb a corner on the left (5.4) or the right (5.6) to get started, then move right into a right-facing dihedral and climb to a small ledge.
Pitch 2
5.4, 90'
Work around the right side of a flake, and then go up a right-acing dihedral to a big ledge with a large flake.
Pitch 3
5.8, 140'
From the alcove formed by the flake, climb a steep corner with fixed pins (crux, often wet) and continue up a shallow dihedral with a two-inch crack. Belay on Lunch Ledge (a large terrace studded with big blocks). Try to belay on the south end of the ledge since the next pitch starts from the south end. This lead is called the Piton Ladder.
Pitch 4
5.5
Climb a corner or the steep flakes out left, then work up and left to belay on a ledge about 40 feet from the end of Alexander's Traverse.
Pitch 5
5.6, 120'
(via Hornsby's Direct Finish)
Follow shallow dihedrals up to a small ledge below a steeper section.
(An alternative—and easier finish—to the Hornsby Direct finish is to cut left on Alexander's Chimney. But the Hornsby Direct finish is nice and direct and offers good climbing.)
Pitch 6
5.8, 140'
(via Hornsby's Direct Finish)
Follow a right-facing dihedral past a roof and many foxed pins to Broadway. The dihedral just to the left may also be climbed, and is slightly more difficult.
(An alternative—and easier finish—to the Hornsby Direct finish is to cut left on Alexander's Chimney. But the Hornsby Direct finish is nice and direct and offers good climbing.)

The route ends on Broadway Ledge.
Descent
There are a few descent options: go right and rappel the Endless Summer Rappel route down the Diagonal Wall to Mills Glacier (I did this when I climbed Kor's Door in 2020); go left and rappel Alexander's Chimney (probably a bit loose); go left and descend Lambs Slide (ice or snow, somewhat steep, probably want crampons and ice axe); go left and get to the base of Zumie's Thumb and climb some more (which is what we did)!
It is possible to access the base of the Diamond by traversing rightward along Broadway Ledge, but it is pretty sketchy in one section. On my June 2020 climb of Kor's Door, we actually tried to traverse to the base of the Diamond to run up the Casual Route, but we were thwarted by a steep and sloughing snow patch hanging above Field's Chimney.

Approach
Steep snow or 5th class
One way to reach the base is to ascend Lambs Slide. This can be quite icy in the later summer. Another way to reach the base is to climb a route on the Lower East Face and traverse in from Broadway, and make this into a nice long day of climbing. This is what we did.

The route ends atop the Thumb formation.
Descent
Getting back to walk-off terrain from the Thumb is a bit complicated. Whatever option, be careful since there is a lot of loose rock in this area and the terrain is not somewhere you would want anything bad to happen. Bolts and fixed pins are in place atop the Thumb for rappel back to the gap. There are a couple of viable options from here.
Option 1: The guidebook mentions that you can rappel back to the top of Lambs Slide. You definitely do not want to rappel the gully (death blocks everywhere), so if you chose this option, it is probably best to start rappelling southward from the actual summit (the guidebook doesn't make this clear). Apparently you can get down by making three double-rope rappels (or five single-rope rappels) southward, and descend the west arm of Lambs Slide back to the main couloir. Descend Lambs Slide back to Chasm Lake (crampons and ice axe would be nice to have, essential in later summer), or climb to the top of Lambs Slide and descend The Loft.
Option 2: (This is the way we went.) Climb a pitch out on the other side to easy terrain. Walk off via The Loft (or, for an even longer day and another summit, head for the summit of Longs Peak— this would involve negotiating the Notch by either a rappel or via Gorrell's Traverse, and then head to the summit on terrain no more than 5.5.). We searched for the easiest and best rock way, and found a pitch of climbing that felt about 5.10 DFU. There are several options that look climbable, but most look 5.10-5.11 and the rock is a bit suspect. Overall, I feel that climbing a pitch out is probably the safest way out, since I am never a fan of several rappels in loose and unknown terrain.

Our bivy
We bivied in Chasm Lake Cirque. What a spectacular place to spend a couple of days—one of my favorite bivy locations in RMNP.
Flora, Plants, Birds, etc.
Although the wildflowers were past their peak, there were still several flowers dotting the landscape. There were also several rosy-finches up in the Chasm Lake Cirque.
