If you live in or visit Southern California, don't hike alone. Yes, the weather is nice most of the time, but it gets cold in the mountains at night, and what happened to Sands is extremely common in both the San Gabriel and San Bernardino Mountains.
When I was 15 or 16 two friends and I got separated from our Big Brother of America who took us up to the San Gabriel Mountains to hike. We had found a small path that led to a small trickle of running water that went over the side of a cliff into a pool of water. I climbed down around the side and was at the bottom looking into the pool, which was only about 2 feet deep. My friend and his brother had remained up top to wait for me. Suddenly I hear a scream and one of my friends had slipped on some algae near that trickle of water and slid down it and over the side of the 20ish foot cliff and into that 2 feet of very cold water. He pops up very quickly from the water completely unhurt and looks up to his brother and yells, "Paul don't try it!" to which Paul answered, "Do you think I'm crazy?"If you live in or visit Southern California, don't hike alone.

California at that time was experiencing rain(snow in those mountains) from "atmospheric rivers"(no idea who coined that silly phrase) one to two times a week and they dropped a TON of rain and snow on us. If he fell, it's extremely probable that the weather had something to do with it.He may also have fallen or had a heart attack or stroke, and the weather may have had nothing to do with his death. The coroner will be trying to determine the cause of death, but it may be a few weeks before we know. Regardless of the cause, very tragic loss.![]()
Even if the weather isn't particularly extreme, you need to take precautions and don't hike unaccompanied. A fall? A couple of days trapped outdoors with a broken ankle, or a tumble into a fast stream can do for you; and if you have a heart attack, if someone is with you they might be able to get medical help in time.
England aint known for it's mountains or wilderness, but there are still plenty of casualties. There was something like 26 deaths* recorded in the Lake District last year.
*I think that incudes watersports as well as hiking.
