Congratulations Diane!
Made a quick run to Yosemite in mid-February, hoping for the light show on Horsetail Fall. No luck there (not enough water for the "fall" to pop into virtual existence), but some clearing mist after a too-minor snowstorm gave me an excuse for a slightly different composition of Yosemite Falls.
Canon 5D III, 70-200 f/2.8 at 70, ISO 200, f/11, 1/60. Tripod. Too lazy to change to the 24-70, and I love extra pixels, so I shot a vertical pano (one aimed higher, one lower) and stitched in CS6 after basic LR4 raw processing.
