So we are planning a trip on Memorial day weekend in either Yosemite or Sequoia Kings Canyon. When we called the Yosemite backcountry office, they were pretty dire about the conditions so we started looking at Sequoia Kings Canyon instead.
We would like to get into the high country a bit and are relatively experienced, although the river crossings of the Sierras are a little bit out of our depth (haha).
This year has been dry so far but its far too early to have any idea what Memorial Day is going to be like.
In a dry year it can be early spring (keep in mind that SEKI is far higher altitude than Yosemite) but in a heavy snow year can still be winter.
Experienced backcountry travelers in the Sierra know you can never plan so far in advance. You are just gonna have to remain flexible until later in the year when its more clear what the snow pack is going to be.
Are you thinking of SEKI from the West? Crossing the Eastern passes that early can be very snowy....Tioga Pass traditionally opens on Memorial Day...depending on snow amounts....if its a dry year overall the Yosemite people were just being conservative...it can be very good then, albeit still early spring.
Lots to consider and every year this stuff comes up...Early Spring is early and no guarantees that there will be access to the high country.
