Conjunction Junction is a focused 60-foot sport climb that offers a concentrated burst of slab and vertical movement, set against the rough textures of Riverside Quarry in California’s Inland Empire. The approach brings you close to well-worn sandstone faces bathed in morning light, with the rock’s subtle grain inviting careful footwork before transitioning to the more demanding upper sections. Starting with a smooth slab, the route immediately challenges your balance and precision. The climb rewards steady pacing as you move onto an apron of slightly steeper slabby rock, where every foothold counts. The final headwall sweeps upward with a series of positive edges that test finger strength and body positioning—the crux. Bolts pepper the route at regular intervals, providing confidence without diluting the need for technique. The last two bolts are shared with the adjacent Function Junction, indicating a confluence of climbs that makes this rock face a compact hub for sport climbers.

Riverside Quarry is a working environment that balances rugged industrial character with engaging sport lines, making each ascent a direct encounter with stone and effort. Climbers who value precision and a clean, technical slab will find Conjunction Junction satisfying, particularly for a quick push either early in the day or as a warm-up before tackling longer routes nearby. The route’s 5.9 rating sits comfortably within reach of most intermediate climbers, yet the crux demands careful placement and smooth sequencing. The single pitch format also lends itself well to short sessions without extensive gear or long approaches.

Planning your visit means preparing for well-bolted climbs but also accommodating the area’s semi-urban setting. Hydration is key as shade can be limited, especially during late morning. Footwear with sticky rubber and a sensitive profile will maximize your grip on the slab sections. Peak conditions usually arrive in spring and fall, when temperatures are moderate. Keep an eye on the quarry’s access policies and any local restrictions to ensure a safe and responsible climb.

Conjunction Junction is a crack-free slab and face climb that invites a measured pace and focused effort. Its location within the Inland Empire’s sandstone outcrops places it within reach of Southern California’s climbing community, yet it retains a sharp character that keeps each move intentional. Whether you’re refining slab technique or seeking a solid 5.9 challenge, this route offers a calculated dance on stone where balance meets power.
