Owner Beware offers a focused, single-pitch trad climb set on the Lower Infirmary Slabs, tucked within the South Fork of St. Vrain Canyon near Lyons, Colorado. This 100-foot route presents a hands-on crack climb that challenges both gear selection and movement with care and precision. Starting on a clean crack that transitions into an exposed step right, climbers are engaged by a bulging obstacle capped by a small overhang before topping out at a solitary tree. The crack's rhythm invites steady, deliberate placements—all within a compact but varied line that rewards attention to detail. A red Camalot fits snugly under a distinctive shrub around the climb’s midsection, a key piece for protection on the route’s more exposed moves. Despite its relatively modest length, the climb punches above its weight with a PG13 rating, warning of some runout sections where precision and judgment guide the lead.

The rock’s temperature shifts through the day, with morning light gradually illuminating the wall’s southern face, warming the slab as the sun rises. The approach trail follows a forested path weaving through pine and scrub oak, with striking views of the South Fork at the base that call for a moment of appreciation before the ascent begins. The descent requires a careful scramble west of the summit tree; the terrain encourages cautious footing as loose rock and brush come into play. This climb is a practical choice for trad climbers seeking solid crack technique practice without excessive committing exposure—though the commitment level is not to be underestimated given the PG rating.

For preparation, light rack options focused on small cams will serve best, balancing readiness with the climb’s limited placements. Footwear with sensitive edging performs well on the slab moves, and timing your climb to avoid the afternoon heat can make the experience more comfortable. The route’s proximity to Lyons means logistical ease, but climbers should prepare for quick weather changes common to the region. Owner Beware is a concise classic that prefers quality over quantity, demanding a precise but measured approach to protect the delicate harmony between climber and rock.
