Sierra Alpine ice/mixed?

I'll be doing some field work in southern CA starting this spring into late June. I'll definitely have my rock gear for my days off but I'm wondering if it will be worth it to bring mountaineering boots/crampons and technical tools? I'm really into ice and mixed but does the Sierra have much to offer in that regard or should I just stick to aluminum pons/ice axe and go rock climbing? Any route recommendations would be appreciated.

My guess is no to the spring ice... but I am new to the Sierras so I will let others offer a more definitive opinion. At any rate if you are looking for a partner I am game. Zero technical mixed experience but have climbed some WI, AI, and snow routes in Idaho and Montana. I also have extra 'pons and some old Charlet Axars you could borrow if you wanted to climb together and just brought your boots.

That is just Lee Vining area, not covering higher elevations.
