Snowpit Observations
More detailed information about the snowpack: 

-Toured today (3/1/17) up TJ Bowl to Mammoth Crest via standard approach route. Still mostly dry surface snow (20cm) comprised of denser (F+) DFs, though a temperature crust could be found in some treed areas that were less protected from incoming solar.

-Dug a test pit below the crest, where there are some quite large cornices hanging over many of the entrances to chutes. Access from below is recommended to scope your line of choice. El. 10600, N (5deg.) aspect, 28 deg. slope.

0-28cm F+

28-75 1F-1F+

75-100 P+

CTH 25 down 28cms, Q3/BRK.

Notable observations: Mostly great skiing in boot top pow on supportable snow below especially below Crest, though isloated windslabs were found in lower TJ Bowl (Child's Play Bowl per Moynier) with hollow drumlike sounds and small shooting cracks. Pic attached.
