Totally agree with Tom on using hiking poles to probe. For many many years I did an early spring shakedown trip up to Merced Lake when there was still some degree of snow in places. If snakes were out they were in a foul mood. there’s a six mile section I came to call rattlesnake alley. I was buzzed twice and saw 8 or 9 others in the spring over the years–sometimes so early in the seasons that they were still barely moving. I hate snakes! I would wear long gaiters and definitely use my poles as probes and as potentially a weapon to ward off any strikes. Often trees were down over the trail and poles are good in this situation. I would also do my best to stay focused and gaze down the trail ahead looking for snakes–especially to the side of the trail. And since spring is the only time I would have a small fire, wood gathering was done with special care.
But for most of the year snakes were a non issue except for certain known areas, like down through the Grand Canyon of the Tuolumne.
