Slab City (Left) offers climbers a unique flavor of Riverside Quarry’s expansive terrain with a focus on slab climbing that feels approachable yet rewarding. This sector stretches from Diagonal Direct to Pucker Power (5.12b R), anchoring the far left side of the crag. Arriving here is straightforward — a dirt road runs parallel to the base, and it’s just a five-minute stroll from the nearest parking area to the climbs. This ease of access allows climbers to save energy on approach and focus on the climbs themselves.

The routes at Slab City (Left) lean into slab style — the rock is less continuous than other parts of the Quarry, giving a playful and technical edge to the ascents. Dynamic moves meld with subtle footwork on angles that require balance and patience more than brute strength. Route difficulties range from 5.8 to 5.12c, providing challenges for intermediate climbers hungry to sharpen their slab technique, while also offering lines for stronger climbers to test their finesse.

Among the most recommended climbs is the first pitch of Feetal Rearrangement (5.8), a welcoming introduction to the slab vibe here. Mantle Marathon (5.10a) and Shattered Dreams (5.10c) invite focused movement on subtly angled faces, perfect for honing precise foot placements. For climbers seeking harder challenges, Peter Principle (5.11d) stands out with its crisp, technical sequences demanding good balance and mental control.

Classic climbs like Cling Thing (5.10b) and Pigeon, The Other White Meat (5.10b) have earned their reputation with clean lines that reward careful technique and composure. These climbs, alongside Shattered Dreams and Peter Principle, form a core selection that highlights the distinctive slab character of the area.

The elevation of the crag at 985 feet puts it within the moderate altitude range, where temperature swings are moderate but climbers should still bring layers, especially for early spring or fall sessions. The wall’s orientation tends to invite morning shade and afternoon sun, making timing climbs to avoid mid-day heat during warmer months a smart move.

Accessing this slice of the quarry is intuitive. Follow the dirt road at the base and veer left until you reach the far edge of the crag. The terrain along the approach is gentle, with no scrambling needed, making it an excellent spot for climbers carrying gear or those working on multiple pitches in a day.

Protection here is straightforward — most routes climb from the ground with good fixed anchors, and sport climbing gear such as quickdraws is your best companion. Because of the slabby, less continuous nature of the routes, having solid confidence in your footwork and balance is key, and wearing sticky shoes will make all the difference.

Descending from Slab City (Left) is typically done by rappelling or walking off depending on which climb you finish on, but climbers should review specific route descents for safety. The rock generally holds well, but attention to your footing on the way down is crucial to avoid slips, especially on lighter scrub or loose gravel patches.

Overall, Slab City (Left) delivers a deliberately paced climbing experience framed by technical slabs and approachable access. It welcomes those intrigued by slab challenges and those looking to escape long approaches for a quick session in quality rock. Whether you are refining slab technique or savoring a classic line like Peter Principle, the area’s balance of fun and technical challenge makes it a prized piece of the Riverside Quarry puzzle.
