length of season

Hi all -

I was planning a trip (my first) out to Hyalite later in March and was beginning to wonder about how long the season lasts out there.  I understand that ice can last though the end of March, but I was beginning to become concerned that this year might be atypical.  Obviously no one can predict 3 weeks into the future, but can anyone give me an idea of how late into March you can climb based on past years?

Thanks!
