Why Descents Deserve More Thought Than Ascents

Most hillwalkers spend hours planning the ascent and barely a thought on the way down. Yet tired legs, gravity and loose ground make descents the most common place for slips and tumbles. In the UK, our hills may be modest in height, but they are often steep, eroded and full of hidden traps. A safe descent begins at the summit, or even earlier, while you are still fresh and thinking clearly. Study the map and the landscape before you commit. The few minutes you spend reading the ground will pay you back with confident, controlled steps when your legs are heavy and the weather is closing in.

Reading Gradient: Contours, Spurs and Slopes

Gradient is the first thing to assess. On the map, contour lines packed tightly together mean steep ground. But shape matters as much as steepness. A convex slope — one that bulges outwards — often hides a crag or a sudden drop below its brow. A concave slope, curving inwards like a bowl, tends to be more sheltered and gradual, though it can funnel you into a boggy hollow. Spurs and ridges are your friends. A broad spur gives a natural line of descent with easier angles and better views of what lies ahead. Look for terrace paths or sheep tracks etched across the hillside. These show where others have found a workable route. If the map shows crags, avoid the obvious gully or scree fan beneath them. Instead, aim for the gentler shoulder or the edge of the steep ground.

Erosion and Ground Cover: What the Surface Tells You

The ground under your feet speaks volumes. Loose scree, often found on the flanks of our higher peaks, is a classic descent hazard. It shifts underfoot and can turn a simple step into a slide. Fresh erosion scars — bare soil, exposed rock, zigzag cut paths — warn of heavy use and unstable ground. Heather and deep grass can hide holes, rocks and boggy patches. Wet grass is notoriously slippery, especially on chalk or clay. Rock type matters too. Gritstone and granite offer good friction when dry but become greasy in the wet. Slate and shale can be crumbly. Where you see widespread erosion, ask why. Often it is a sign of water concentrating or a path that has become too steep. Better to find a line on firmer, less worn ground, even if it adds a few metres to your route.

Water Flow and Boggy Ground: Following the Wet Signs

Water is the great shaper of our hills, and it leaves clues everywhere. Look for bright green moss, rushes, cotton grass and dark, saturated peat. These plants thrive where the ground is wet and often pathless. Peat hags and groughs — the deep, eroded channels of the Pennines and Scottish borders — can be a nightmare to cross. Avoid flat col floors and valley bottoms where water gathers. Instead, follow spurs, ridges or the edges of slopes where drainage is better. After heavy rain, water tables rise quickly, and what looked like a dry route on the map can become a quagmire. Listen for the sound of running water, and watch for small streams appearing where none are marked. If you must cross a boggy area, step on tussocks, use your poles for balance, and never assume a patch of green is solid.

Choosing Your Line and Staying Flexible

Bring your observations together before you descend. From the summit, trace your intended line with your eyes. Does the gradient ease? Is the ground cover consistent? Where does the water flow? Use your map and compass to take a backstop bearing — a feature such as a stream, a wall or a track that will catch you if you drift. Handrails, like a ridge line or a boundary fence, make navigation easier. But remain flexible. A line that looked good from above may reveal a hidden crag or a boggy patch. Be willing to traverse sideways to find a better way. Test the ground with your poles and your feet. If it feels wrong, stop, reassess, and choose another option. There is no shame in retracing your steps to the summit and taking a different route.

Putting It Together: A Descent Checklist

Before you drop off the top, run through this quick mental checklist:

• Gradient: Are contours tight or widely spaced? Is the slope convex or concave? Aim for spurs and shoulders, not gully lines.
• Erosion: Look for loose scree, bare soil and worn paths. Choose firmer, less damaged ground where possible.
• Water: Spot green moss, rushes and dark peat. Avoid flat hollows and valley floors. Follow ridges and edges for better drainage.
• Escape routes: Identify a backstop bearing and a handrail. Know how to bail out if the ground turns nasty.
• Flexibility: Be ready to change your line. Test each step, and never commit to a descent that looks unsafe.

Read the landscape before you need to. A little time spent studying gradient, erosion and water flow will turn a nervous descent into a confident one. Your knees, and your safety, will thank you.
