Alfred Wainwright on Bleaklow:
"...a few isolated boundary posts serve as waymarks over a rising desert of peat groughs, heathery hummocks and boggy hollows. Progress is slow and made only by a series of trials and errors in a confusing terrain. Reliance cannot be placed in following bootmarks in the mud, which may be the wandering imprints of lost pilgrims....My own experiences on Bleaklow were dreadful, one on a day of sluicing rain and another of drifting mist. Many other walkers have reported this hill as an unfriendly and cheerless place and rescues have been necessary."

When wet (and that is almost always) you sink up to your knees in liquid black peat at every step and flounder - not nice at all.
