It is certainly easier with shovels and snow saws, but unfortunately, we aren't so lucky as to be particularly well-equipped when we start out. Perhaps with certain Pokemon it could be done, but generally speaking the ones we start with are not those.
Digging a cave out of a snowdrift or making a quinze are probably the only real options.
