And geological science is coming around to that point of view. Especially with massive forces such as glaciation involved. However, that is not a violation of uniformitarianism as many YEC types like to claim, it just means that we are still learning about geological processes, because we haven't been studying such for very long (long as far as the Earth is concerned). We'll discover new processes going forward as well. But the new processes also happened in the past (there are records of glaciation from hundreds of millions of years ago, for example), so uniformitarianism is not violated - uniformitarianism simply states that geological processes that are happening now also happened in the past.
However, it does mean that uniformitarian geologists are being forced by the evidence to move closer and closer to catastrophism, which, as you well know, has been a creationist prediction all along.
