Inspired by @thenomadicartist's recent trip report, I set off on a sunrise mission on Friday morning. Not a ton to add to their excellent trip report, but a few things to note.

Mount Si to Roaring Creek to Mount Teneriffe to Kamikaze: I started from the Mt. Si parking lot at 5:30 a.m. which was admittedly a bit late for sunrise. I was the second car in the lot. Took the Mt. Si trail up to the Roaring Creek/Talus junction and went with Roaring Creek instead. The trail is mostly flat and in great shape. Somewhere along the way, I was passed by a group of 7 trail runners and 2 dogs which was a bit of a surprise for 6am! I then connected to the Mount Teneriffe trail for some nice uphill before descending briefly on the Teneriffe Falls trail. Missed my turn almost immediately as I was heading towards the falls but quickly corrected. First time on the Kamikaze trail and I was surprised how easy it was to follow. I only got off trail a bit one time. It's well established and at times feels like the Old Mailbox trail but less chewed up terrain. There a couple of mini viewpoints along the way and even a point where I thought I was at the top but then tucked back into the forest. As mentioned, there are a few patches of snow near the top, but easily avoidable or firm enough to walk on. I made the summit at 8:30 a.m. having seen some of the sunrise from the trail. Summit is entirely snow free as mentioned and the views are some of my favorite on the i90 corridor. Baker, Glacier Peak and Rainier were all visible and I spent roughly 30 minutes of solitude enjoying the views. 

Mount Teneriffe to Mount Si: I had initially intended to follow the same route as @thenomadicartist and take the main Teneriffe trailhead back down and pick back up with the Roaring Creek trail. Some snow patches still exist, though this could change depending on the snow this weekend. Once at the junction for Mt. Si, I looked at the map and felt like (with some very loose math) that it wouldn't be much of a difference to tag Mt. Si as well. Maybe not a great idea in hindsight since it was about another 600 feet of gain to get to Si but I was feeling good. This section of trail has had snow on previous trips but was completely snow free today. There were about 7 or so people in various places at the summit of Si when I arrived, so I had about 4 hours of solitude from the trail runners on Roaring Creek before I saw anyone else again. Took a quick photo of Rainier again and then headed down the main Mt. Si trail. Passed a total of 97 more people on the way down including one hiker heading down who I passed and 1 who passed me. Everyone else was head up. 

Carried spikes, jacket, gloves but did not use. The summit of Teneriffe was a little breezy but I didn't feel the need to break out the jacket. I switched to shorts once I had descended a bit (thank you convertible pants) which is a wild thought for February (fingers crossed for return to winter soon!). 

Garmin stats: 12.4 miles, 4,823 feet of gain

My hiking group started from Teneriffe trailhead and hiked on the base of Mount & Little Si to a mossy rocky outcropping we call Moss Vista for a 7.8 Mile hike today.  Only 1 other car was in the TH lot when we started out at 9:30.   It was 44 degrees with partially cloudy skies.  The bathroom facility was open and clean.  The entire route was hard packed soil, some with a cushion duff of needles and other areas rocky.  We followed Mount Teneriffe, Roaring Creek, Mt Si , Douglas Fir and Boulder Garden Loop trails for an out and back hike.  After the recent cold spell the ground has warmed up and there was no evidence of icy or frost heaves.  Trail traffic was really light, except a short section of the Mt Si trail where we met hikers ascending and descending.  Getting to the rocky out cropping was more challenging this year with several blow downs to to scramble over. This area is not maintained as the main trails.  We noticed new bolts and screws mounted in newly cleared areas (moss removal) at out lunch spot. 
The wind really whipped up as we were enjoying a lunch rest break looking south to Mt Washington, Taylor Mtn and Rattlesnake Ledges.  This precipitated us packing up faster than we were planning as everyone chilled down and we were concerned about falling branches.  After we packed up and were heading back up on the Boulder Garden Loop we met two rock climbers who were headed down to the base of lunch spot for rock climbing.  They indicated someone was most likely installing new anchors.  We had no wildlife sightings today.  14 cars were in the TH lot when we drove off at 2:20.  Another fantastic day out in nature with friends.

Parking lot is large with a clean well-stocked bathroom. On this cloudy Friday I passed only about a dozen folks on the trails I used. I decided to make this a loop using the Mt. Teneriffe, Teneriffe Falls, Teneriffe Falls Connector, and Roaring Creek trails. The Mt. Teneriffe trail begins wide with a comfortable grade, and after the turnoff to the falls it becomes significantly more steep, rocky, and narrow. There's just one spot along the way with a nice view of the valley and some mountains, and you can hear I-90 traffic the entire way until it's drowned out by the noise of the falls. The highlight is definitely the falls themselves - super full and majestic right now, and you're so close to them you can feel their mist and their power. On my way back down I decided to check out the Teneriffe Falls Connector Trail and Roaring Creek Trail, making it a loop. I was so glad I did! It cuts off about half of the steep rocky trail, and replaces it with a wide, flat, easy grade trail that is greener, mossier, and quieter, with at least two nice sturdy bridges and several small creeks that provide interesting water features and gentle creek sounds. I passed no one along this part of the loop. The distance and elevation gain are about the same. Next time I will likely take that trail both directions, or start at the Mt. Si trailhead and explore the trails from that direction - lots of different trails in the Mt. Si NRCA to explore!

My party of two hiked a nice lollipop loop today from the Mount Si Trailhead. Overall about 11.5 miles in 7 hrs, with 4000' of elevation gain.

ROUTE: We started up the regular Mount Si Trail, then took the Douglas Fir Trail to the next junction (North's Road), where we cut up to the Mount Si Old Trail. We followed the old trail to the top, then passed the Haystack and took the Si-Teneriffe connector over to the Mount Teneriffe Trail. We followed this down to the next junction and took a side trip to visit Teneriffe Falls. Returning to the Mount Teneriffe Trail, we continued down to the Roaring Creek Trail, which we then followed back to the Mount Si Trail and down to the car.

Teneriffe Falls is running pretty good now, and there is no snow at the falls.

TH: Nothing much to report, there are plenty of potholes in the parking lot. Plenty of people hiking the area today, there were around 20 cars in the parking lot when we started at 8:30.

BLOWDOWNS: Most of the trails had plenty of small branches on them, but we didn't encounter many serious blowdowns. The main exception was on the North's Road Trail - at least 20-30 blowdowns here, but fortunately almost all are step-overs.

SNOW: Started at about 3000' on the Mount Si Old Trail. There was about 5-6" of snow in the summit areas of Mount Si and through most of the connector trail toward Teneriffe. Snow gradually lessened on our way down the Teneriffe Trail, until it disappeared completely at about 2800'. Most of the snow was new and we laid in the first set of tracks across the connector trail this morning.

GEAR: Gaiters were helpful in the deeper snow on the Si-Teneriffe Connector, but you could get by without them now that the trail has been tracked out a bit. Spikes were not strictly needed, except to climb over the boulders at the south-facing Mount Si viewpoint. But that was mainly because the snow was new and providing good traction. It will get more slippery as it gets tracked out, so spikes are definitely recommended. Snowshoes would have been overkill today.
