I am considering a trip up Mt. Mystery and for some reason I have become intrigued with solo glacier travel which is admittedly, stupid I do however, put in the time researching. Mystery glacier is said to be stagnant, meaning it does not build up enough new ice to force it to flow (slowly) downhill, and therefor one might conclude that it does not form crevasses. I went with that assumption this past spring on the Upper Paradise glacier and all went well (I also, discussed the trip with a park ranger) But I have found evidence from a trip report made in 2023 that clearly shows crevasses on the Mystery Glacier and I want to make anyone reading this trip report aware of that. It's a long post about a 3 week trip so a search of the word "mystery" on the page should get you there fast. I could believe that in early season after a good snow year that those slots would be filled up. Here's a link to that 2023 trip report: https://www.nwhikers.net/forums/viewtopic.php?t=7984783
