Alluvial Fan and Indovalley are my go-to spots for a relaxing picnic spot. My family has been coming here for years and I always make a stop here. It's changed over the years with floods and reconstruction, but its still an amazing spot. There is a trail to Lawn Lake near by as well. Big horn sheep can be seen... More

I have studied this disaster for years in geology and natural hazards classes. Truly amazing and unable to imagine the force of the water and extent of distruction unless you go and see the size and quantity of boulders. The fall is beautiful and massive!

Get out and explore Alluvial Fan. In addition to an interesting place, it is also a great place for photo taking.

I'm offering this post to remind you that from the descriptions provided, it is easy to dismiss this area as not being as much fun as some of... More

Thi alluvial fan was originally created by an earthen dam breaking in the 1980's. The Flood of 2013 renewed and refreshed this fan and changed the area once again. It is a geologic erosional marvel that is easy to see and enjoy. It is more challenging to hike after the flood, so access is limited by your physical limitations. There... More

Climbing the stones and boulders left behind by the glacier is a very unique experience unlike the regular hiking. Lots of fun for kids and adults. Get to soak your feet in the refreshing water cascading down.

You need to stop here when riding through Rocky Mountain Nat'l Park!! This will be one of your first stops and it's an easy walk to the falls from the East Parking Lot. You should also read the story board to learn what happened here and how this part of the park was formed, it provides great insight into the... More

I am always drawn to this area. Maybe it's not as pretty as it was after the Lawn Lake Flood, but if you were here before the 2013 flood you can really appreciate the force needed to move all of that rock around. Easy trail and kids enjoy it.

Seeing the result of flooding water and the size of the boulders moved by the water is amazing. A great sideline stop on a Trail Ridge Road trip.
