Day 13-Missoula, MT to Lolo Hot Springs, MT-40.17

We were on our bikes and moving by 8:10 this morning to beat the wind and heat. We feel we need to leave early because we are expecting to gain 1000 ft. in elevation in this 40 mile journey. The roads, 12 and 93, that we took from Missoula to Lolo was very busy reminding us of road 15 in Indiana. We lost route 93 at Lolo and the rest of the trip was very pleasant. It was one of the most beautiful rides of the trip so far. Even though it was uphill, it was a gentle grade with light winds and scenery was gorgeous.
A friend of mine described bicycle touring like this. If you encounter someone who says, "Are we there, yet?" A bicycle tourist can answer, "Yes, we are there...all the time!" The enjoyment is in the trip, not the destination." How true!
Lolo Hot Springs is a unique place. We checked in at the RV park in the village, set up our tent and went directly to the restaurant for a late lunch. After lunch we changed clothes and sampled the hot springs. The hot springs are made up of 2 pools, one is an indoor pool 104 degrees for soaking and the other is an outdoor pool at 85 degrees. It is particularly pleasant to soak in the hot one for as long as one can stand it and then go immediately to the cooler one. We enjoyed the hot springs for most of the afternoon and then took another evening dip before bed.

How many of these are elements on the Periodic Table and what are their abbreviations?
