Howler, also known as Old 55, stakes its claim on the lower face of Split Dome, a striking granite feature perched above Jackson Creek in Colorado's Rampart Range. This is the leftmost and most demanding of four sport lines that slice through this stone face, immediately signaling to climbers the test ahead. The route begins with a steep pull that pushes your endurance early on, setting the tone before the key crux arrives near the third bolt. Here, a subtle scar in the rock creates a pocket-sized niche just wide enough for finger-sized cams between 1.5 and 2 inches, offering a crucial piece of protection if you’re carrying a traditional rack alongside your quickdraws.

The rock around this section challenges with its textured surface, demanding precision and steady footwork as you negotiate a sequence where body tension meets calculated reach. Above the crux, the final stretch slides into less intense climbing, allowing some recovery before pulling over the lip. From the top, the descent involves a straightforward walk-off to the right, leading climbers back to the base where the other three lines invite exploration. Those routes offer slightly less intense challenges, perfect for warming up or extending your session in this rugged area.

Located near South Platte, this climb enjoys a southeastern exposure that catches the morning sun, making early starts ideal during the warmer months to avoid afternoon heat baking the rock. The approach is relatively short, yet the rugged terrain demands sturdy hiking footwear and attention to footing as you navigate down from the parking area. Bringing six quickdraws covers the protection needs here, but adding a small cam or two might provide extra insurance around the scarred crux.

For climbers seeking an accessible 5.9 with a bit more bite than typical sport routes, Howler serves as a compelling test on quality granite with moderate commitment. The route demands focus but rewards with confidence-building moves and the subtle satisfaction of threading protection in a natural crack feature. With a handful of votes online attesting to its character, it remains a discovery for those willing to push leftward on Split Dome’s lower wall. Pack water, time your climb to enjoy cooler morning light, and come prepared for a brief but memorable line that challenges and captivates in equal parts.
