We need a bit more to go on.
Hello and welcome to the RTA forums !
With thousands of alternative routes and attractions your info is a little vague to start offering meaningful suggestions. We don't know if you have any destinations in these States which are huge, what your interests are or how long you have for the trip. If you could start with telling us the basics of your trip we can then offer some meaningful advice rather than just throwing out a random list of places. You will alos be passing through other great States to get between these points with lots of great options, Utah and Idaho as two examples.
Thirteen days to Denver ?
From home it will take a day and a half [or so] of driving where depending on which route you took, you could spend the night in Lubbock or possibly Amarillo. Albu to Springfield is a minimum 2.5 day drive but you don't say how long you are planning for this leg. If you take US550/CR5500/US64/491/191 you could stop the night in Moab, home to neaby Arches and Canyonlands NP. [If you have more time you will be close to Mesa Verde NP] Moab to Twin Falls ID is around 450 miles and would give you time to see the Snake river canyon and Perrine Bridge and again time permitting, nearby is Shoshone Fall aka The Niagara of the west. Twin Falls to Bend is a comfortable day on the road, but have you considered time to visit Crater Lake ?
East of Portland is the lovely Columbia River Gorge as you make your way to Olympic NP. You should then allow an overnight stop to get to Yellowstone, Coeur d' Alene being a nice place to break the journey. We usually recommend at least 3 to 4 days to spend in Yellowstone and it's neighbouring park, the Grand Tetons. If you spent your last night in the area in Jackson WY you could make it to Denver in a day, although you could take a detour to RMNP.
Woah ! Do you mean that you need to be in Denver for the 10th ? If this is the case you are biting off way more than you can chew in my opinion! You have 7 to 8 days of solid driving and you really need 3 days in Yellowstone leaving you only 3 or 4 days for extra sight seeing. Thats a heck of an imbalance between time in and out of the car and I would seriously reconsider going all the way to Oregon and Washington with so little time. Why not take a more relaxed approach to Yellowstone and take in a lot more sights that you won't have to enjoy through the windscreen.
