Taken 4/2009 in Yosemite National Park. The sign my husband is reaching for is a flood sign dated 1/2/1997 the last time Yosemite flooded. My husband is 6’3" tall and has long arms so you can just imagine the amount of water and force it brought with it.
The snow melt off, along with the rains are causing the rivers to rise once again (thanks shootinmickey for the info).
here’s the link to the yube tube video showing the 1997 flood. Sorry I am not so good with linking things.
