STOP, Hammer Time

June 8th, 2012

FILLMORE, UTAH – [Guest Bloggers Matt Peppers and Will Cary]

On the morning of the 8th, all seemed well. Much like days before, we all arose and began to pack our lunches for the day. However, as we piled into the car, an ominous light started to blink on the dashboard. Low tire pressure. Concerned, Dr. Judge pulled us into a nearby gas station and checked the tires. Much to our dismay, the left rear tire was 10 psi lower than it should be, a repeat occurrence from a few days earlier. Not wanting to jeopardize our upcoming Mystery Fun Day, Drs. Judge and Pollock made the decision to take the car into a repair shop to have the problem diagnosed. While they were gone, they left us to wreak havoc upon the KOA Kampground. We started by swimming and relaxing by the pool, and ended by swimming and relaxing by the pool. All before lunchtime. We retired to our individual cabins to enjoy the lunches we had packed a few hours earlier in glorious air conditioned komfort.

 

Around 1 pm, the professors returned and it was business as usual. Even though we had lost half of our day to a small hole in the tire (curse you, basalt!) we rushed out to mob Kevin’s project for the afternoon. Arriving on the cinder cone at peak temperature made for a challenging work environment (especially after having spent most of the day in a sun-induced stupor) but we turned the afternoon into a very productive, albeit rushed, day. After reviewing the wall Kevin had used to map his xenoliths, we spread out and tried to collect as many of the 16 different types as we could find. After a few small injuries, stumbles, artistic work with a rock hammer, and some sore hands trying to pry the xenoliths out of the uncooperative host rock, we amassed a small mountain of samples for Kevin. As Whitney struggled to bag and record the samples in the gusting wind, the rest of us made one last sweep of the area for any xenoliths to claim.

Aptly named, the "Avocado" xenolith inspired some dinner choices this evening.

We trooped back down the van, and made the dusty trek back to the kampsite, just in time to shower and recover before we left for dinner at six. After a quick stop to pick up a package containing some hardier field notebooks we went of to dinner followed by a stop for ice cream, where the professors revealed the Fun Trip they had planned for Saturday. We will be driving down to Bryce Canyon on the morrow to spend the day in the park. None of us have been there, so it promises to be a unique experience for us all!

Sailing the Basalt Isles

FILLMORE, UTAH – [Guest Bloggers Whitney Sims and Kevin Silver]

As we arose for our fourth day of field study, the morning was chilly. However, this was to be short lived. A clear day unleashed the full power of the sun upon the Black Rock Desert as we parked our van and began our trek onto the lava flows once again.  It was Whitney and Matt’s day to lead again and the group was split in two to assist each of them.

Matt’s group was comprised of Dr. Judge, Kevin, and Will. Their goal was to look at the walls of the lava channel to find any structural features and to study the islands of basalt that were scattered across the floor of the lava channel. From there, they were planning to travel west towards a portion of the map that showed faulting near the end of the lava channel. Instead, they quickly deviated from the plan as the floor of the lava channel closer to the cinder cone showed great promise. Their day was spent tracking and measuring fissure fractures that ran both perpendicular and parallel to the walls of the lava channel. Many of these fissures were found to run right through the basalt islands. In addition, a large fault was discovered above the cliff face. Due to the wealth of data and the absolute lack of shade the study site provided, the work was very tedious and many of us, most noticeably the fairest-skinned of us, began suffering from exposure. It was a most joyous occasion when our two groups were reunited once more and were heading back to the van. Despite her preconceptions of horror, Dr. Judge found that accompanying the three boys in the field was nothing but pleasant interactions and behavior on the most professional of levels.

Whitney’s group was comprised of Dr. Pollock, Tricia, and Whitney. Their goal was to collect samples from different sections of the lava channel while travelling west to determine where the lava channel ended. They came upon what is believed to be the western breach of the flow that showed significant promise to Whitney’s project. Upon their trek, they came across a major fault that Dr. Pollock was really excited about.

The day was very productive and rich in data. It has become apparent that Matt currently holds the equivalent of three I.S. projects in his data and thus will not graduate in 2013. Whitney’s project is proving to be quite complex as Ice Springs is proving to hold some unusual structure and complexity within its flows. There is no certainty what future days in the field will reveal.
